Ok, so I've been playing with the various roms and whatnot over the past couple of months and I'm just curious to see what everyone's opinion on the various modems are, specifically if you AREN'T on T-mobile.
I'm using Simple Mobile and using ICBINB.5 which has the KF2 modem, and I've found that I have a lot of time it's "(Searching)" where as with the KD1 modem I didn't have nearly the problems. I just figured I'd ask before flashing the modem back to KD1 if there is any better option for non T-mobile users.
And yes, before you start saying Simple Mobile IS T-mobile, you are correct, but I can promise network speeds aren't nearly as fast and it seems to have a slightly smaller coverage area. I don't know what kind of deal they have going, but I can promise that T-mobile and Simple Mobile are not equal in network.
As a general rule, and because they're interchangeable, most just flash and test in areas they use their phones most often.
There isn't a surefire modern that is the "best" for everyone... kf2 works well enough for me in my home area, but I've heard some prefer kc1...

as many of you know att is throttling speeds for unlimited data users.
changing the apn works to get unthrottled but only if your on hspa+, so areas with lte force you on lte and you are still throttled.
I noticed some roms have a "network mode" option to force hspa or lte. (under access points I think) - this option isn't available on the stock att rom
I am asking that somebody release just that feature in a rom if possible.
personally I'm trying to stay as stock as possible
thanks guys!

Use a rogers rom. It's the only way. Also this belongs in q&a
Only development related topics in the dev section please. (As in a rom, kernels, mod that you have actually created and ready to be downloaded)

Hi, I have been reading some posts in the Radio thread reporting that they are using the T-mobile Modem. It was unclear whether they had it working on the T-mobile network or just using the modem on the ATT network.
Is there anyone here using the Galaxy S II Skyrocket on T-mobiles 1700Mhz AWS 3G band and getting internet and sms and everything no problem?
I just want to make sure before I go out and purchase one for a lot of money and not have it working.
Yup I believe that the Skyrocket and the TMO SII are the same phone or at least have the same radio
Yes, you can use the t-mobile modem on the skyrocket and connect to t-mobile 3g. There are people on xda that have done this and confirmed working. The modem chipsets are different though.
There is one thing though. The skyrocket modem (mdm9200) supports 700/1700/2100 on LTE which is the same frequency that t-mobile uses on 3G. My concern is that although it will work since it is the same frequency, the skyrocket modem uses the 700/1700 band for LTE and not 3G, but 2100 for 3G and LTE. The t-mobile sgs2 uses the mdm8220 which supports 1700/2100 for 3G. I don't know enough about the particular power/design differences to say if this is a safe thing to do for extended periods of time. I heard of a few people having problems with their modems after flashing tmob modem on their skyrocket. Don't know if it's connected to the hardware differences.. just a caution. Make sure you have warranty or insurance coverage before you try
I'm going to buy the phone secondhand and thus I will not have warranty or any return policy hence I am worried. I wanted to make sure that it works before I go out and purchase the phone.
Were the people having problems the people who were still on the ATT network? I plan on using the phone strictly on the T-mobile network which I hear is also going to be putting out 1900Mhz 3G in certain markets due to the failed ATT merger and I happen to be in one of those large markets.
I have seen this question more than once but never an answer to why...with the two phones being nearly identical, what is the draw causing some tmo users to want the 727 over the 989?

Around here it is cheaper and also I hope that the phone will work with non-smartphone data plans on T-mobile because T-mobile locks out their own smartphones to certain data plans.
As I've said, others have reported it to be working. However, I don't think there are enough people doing this to give a clear idea if the tmob modem is having any adverse effects on the skyrocket modem. Maybe open a poll thread to get a better idea?
One of my customers came in with an unlocked and rooted sky rocket, any idea as to how to get it off our edge?

This is for everyone.
IT HAS TO RUN A TMOBILE SGS II MODEM. The radio has the capability, but the modem.bin for the SR doesn't activate AWS/2100. Flashing a T-Mobile modem will fix that though.

Just beware of the sbl.bin (Boot Loader). Do NOT flash the sbl for the Hercules on the Skyrocket. Everything else appears to function the same.
(I've been researching if I should get a Skyrocket or Hercules)

As the title says! Now by combo im referring to ROM + RADIO + KERNEL!
A good example would be tspx23's [Combination juggernaut 4.1/faux kernel NOT overclocked/KL1 Radio] which gets 4G on the West Coast.
The phones been out for a while so i'm just trying to gather info before I buy the phone tomorrow. Thanks again!

Not to be daft, but if you're going on T-Mobile why are you bothering with a Skyrocket? Yes I know you can get it to work on T-Mobile, but unless you're getting a SPECTACULAR deal on an unlocked Skyrocket or you absolutely need a SD Card, why not just get the Galaxy Nexus? It has a better screen, nicer physical profile (IMO) and it's the current flagship Google device, meaning you'll get all the updates before everyone else, not to mention it's only $350 and a truly global phone. My wife has it on a monthly 4G plan and at times I get jealous of it (except for the times when she has an Edge connection while I have HSPA+, but that's a carrier issue, not a device one.)
Just throwing that out there..

I'm already on T-Mobile but could only find a good deal on a Skyrocket sadly. I already got it not i need to do all the mods and what not.
Should just be as easy as flashing the blaze radio from the development thread. All roms should work, including the stock ROM. Flash the recommended kernel for that ROM, hint use ones the Dev told you works great. May have to configure the APN for TMobile if flashing the blaze radio didn't do it for you.

would you please share your average data speeds ? download and upload ? and how does it perform compaired to T mobile phones ?
ROM has no effect radio is dependant on your specific area
Kernel won't change things up for your data speed either
Try your own combos see what works for you. Reported

Basically if you have the OPTION on your OWN to pick depending on the server your on I would suggest getting the own for your service like if you on AT&T go get the i727 if your on T-Mobile get the S2 cause the chances are your speeds are going to be best using the phone made for the server you have chosen. ME on the other hand had LIMITED option due to circumstances I was offered to be on sprint with a parent but was cut off half way of summer so i go back to my original parent who originally took me in T-Mobile and was stuck with a sprint phone the "Motorola Photon 4G" which thanks to a dev on XDA was allowed to unlock the SIM slot for DOMESTIC GSM (USA) with that in mind i liked it but data speeds were sad so i grabbed the i727 and unlocked it so here i am. I will give you output on the speeds once i find stable Combination.

I know that....I would all day anyday use a T mobile phone with T mobile or an AT&T phone with AT&T...especially with these sophisticated devices...I always see here people unlocked their skyrockets fine, flashed TMobile radios and report crappy data speeds and awful coverage...So I'm asking if anybody did use t mobile with skyrocket and data working fine (no crappy download or upload speeds)

I can't get a decent 4g download speed either. I'm currently on Embryo 5.1 and Kernel CYMBALINE-RD03-2.6. I've tested most of the radio that have been posted and still only getting around 550kbps dl and 25kbps ul on all of the radios. Getting over 10Mbps dl and ul on a tmobile phone next to it. Maybe my settings are wrong or something, but I've dial *#2263# and forced it to WDCMA 1700.
does anybody have GPS issues with lack of accuracy and long time to lock? i've never had good GPS performance with the skyrocket on tmobile radios. (i never ran this phone on att network and att radio, so i do not know if GPS performance is any good on ATT radio)

I'm getting about 9mbps download and 2mbps upload as the normal speeds.
Wouldnt know about other tmobile devices
I am running PA JB latest build on my infuse, and i have data plan from AT&T, wife has SkyRocket (S2) without data plan.
To compare the data speeds, I powered off both phones, pulled out my sim and put in SkyRocket, powered up, then enabled data in settings,
Still, it doesnt get data enabled, tried rebooting still no use.
Why isnt my Sim in Skyrocket getting data enabled?

Why are you asking in the infuse section? I understand you have an infuse but the problem is related to the skyrocket... so you should ask in he skyrocket thread as they would know....
But since I do have an lte phone k can tell you the problem...
Lte phones use different apns then the rest of atg smart phones...they use pta APN, in order to use pta apns you have to call Att and enable lte for your account (which is free and doesn't cost anything extra...you just gotta say you got a skyrocket and need to activate the lte, they will ask for the imei...give it to the
If it still doesn't work then go to your nearest Att store and get an lte compatible sim...also free, but the one that comes with the infuse works for lte...if it says 3g on the sim it won't work

Thank you for ur explanation. My remaining question, now that I know infuse doesnt support lte and skyrocket does, even with any custom ROM on infuse, I wont be able to get the high speeds which skyrocket can give.. rt ? OR if i get lte compatible sim and still use in infuse, (and flash latest JB/ICS ROMS) will infuse also can give lte speeds ?
thanx again

Nope. The ability for a phone to use the lte network is in the phone's hardware. No amount of hacking and reprogramming will make the infuse use lte.

So, if I use skyrocket, i get much faster speeds than any ROM on infuse ?? What's the speed difference like in Mbps
I don't know. I don't have lte. I know speed is determined not just by the phone but the signal, the quality of the signal, the amount of traffic using the signal.
Of course this is a question you can answer yourself....
Do a few speed tests with the infuse and then put your sim in the skyrocket and enable the lte with at&t and do a couple speed tests on it.
Just remember each speed test uses about 20mb of data.
Then report your findings. I am kind of curious.
Sent from my SGH-I997 using xda app-developers app
On average with an infuse you'll get about 8mbs down top...I usually average 6mbs down on an infuse and 1-2mbs up...most I've gotten is 3mbs up
With lte...I've gotten 23mbs download speed and 11mbs upload speed...and never lower than 20mbs down and 9mbs up... (only ran speed test six times) but I've seen people report and show proof of 80mbs down...
but that's only if you are in an area that has lte coverage...not everywhere has lte...if lte isn't in your area you'll end up using hspa+ or whatever is the highest speed in your area

I ran with Infuse as it is, At home getting 1-3 Mbps range with several tests
Called ATT to provision the sim for LTE speeds, and ran with Skyrocket. And getting 4-7 Mbps range. Probably my home area isnt that covered with lte (even though ATT claims). So, looks easily 2-3 times speeds with LTE. I will probably use Skyrocket as long as wife allows
