Is 3G software or hardware? In otherwords, Can a GSM PDA phone edition be converted to 3G? If 3G works with GPRS, why not?
Therefore will we soon see a 3G SD card similar to a Wi-Fi card?
Is there a XDA or i-Mate 3G on the cards any time soon?
Thanks

3G or UTSM is a new network the name is because it's the 3th generation of wireless phone networks
the first ones were analog much like directed walktalky's really
2th one was gsm and CDMA
.....
so no it's not software
it operates on a different frequency band
and yes 3g phones are backward compatible so they also works
when there is no 3g service reach
this is the upcomming xda 4 device which support 3g

what 3g really offer that 2g dont is
video phonening
and much much faster datatransfers
this is the upcomming xda 4 device which support 3g

Hmmmm...that looks like a printer to me
I have a 3G data pcmcia card from Orange and I have also tried Vodaphones one.
I'm not impressed with the speed.
It keeps being touted as "broadband for your phone", but it's nowhere near there yet. I have yet to see it reach ISDN speeds.

The Froyo update for us might give us HSPA+
With all these Android 2.2 phones coming out, it may be even longer before we see the Froyo update. Just my opinion.
Do our phones even have the ability to use HSPA+?
I already get an "h" on my phone where it previously said "3g". No even in a major metro -- Des Moines IA. I use this ROM: http://forum.xda-developers.com/showthread.php?t=856561
yes att disabled this.
that is why we flash to i9000
In this article they say that are devices are not compatible
"Unfortunately, just like with HSPA+ on T-Mobile, existing HSPA-compatible devices will not be able to utilize HSPA+, but AT&T is set to remedy that with a whole lineup of HSPA+ ready flagship Android devices – Motorola ATRIX 4G, Samsung Infuse 4G, HTC Inspire 4G, a Motorola tablet, and others. Overall, AT&T is set to release 12 Android phones in 2011, between 5 and 7 of them being HSPA+."

So what you are saying is that ATT is the culprit and our phones are hardware compatible but ATT has forced limitations to neuter our bandwith usage?

you got it.
I think you guys are confusing existing HSPA (currently supported) with the new HSPA+ (just starting to see support).

Idk about offical att fw. I care about the network improvements

That's what I thought, because I was pretty sure our devices weren't HSPA+ capable, just HSPA capable and that it would require the use of different bandwidths and or antennas to work.
What at&t has done is enabled HSDPA and disabled HSUPA which is part of the HSPA specification. The radio in the phone is capable of HSPA speeds up to 14Mbps but not higher AFAIK.
at&t just doesn't release radio firmware that have the faster uplink speeds enabled.
EDIT: Excuse me, the Captivate can't even do 14Mbps. It is locked at 7.2Mbps down and 5.76Mbps up.

Just so you know, HSDPA is the downstream bandwidth and HSUPA is the upstream bandwidth.

I'm well aware of the differences between the two. Although due to the increased upstream speed and thus reduced latency, HSPA tends to have faster downstream speeds than HSDPA alone as well.
Hey is there a way to switch between using 3G and 4G? I know there is a use only 2G networks option but what about 3G/4G? Thanks
I don't think so...
To my understanding, T-Mobile uses the same network technology for both 3G and 4G (HSPA+) so turning off 4G would also turn off 3G. And if that isn't the case, it still wouldn't make sense to turn it off. It's only affect would be slower internet speeds. I could be wrong here though, lets see what the other posts say.

I think you're right BioRivit. Unlike the switch between 2G and 3G, which involved totally different frequencies and underlying technology, 4G is basically the same technology as 3G, except with a few modifications that allow a faster speed.

Ok thanks guys. I guess my real question was supppsed to be how do you tell if you are on tmobile's 3G or "4G". I feel like I've never seen a 3G icon in the status bar, only 4G. Thoughts?
T-Mobile uses the 3g network to transmit 4g. Unlike Verizon or Sprint which have a structural difference between 3g and 4g, T-Mobile is using the 3g network with data compression. This is how they expanded from 3g to 4g instantly, no change in network structure. You won't see 3g again if you have a 4g phone like the G2x. You can only use Edge (2g) or 4g. Hope that helps.
Alright thanks guys
I thought I can connect my 4GS onto the other UMTS network, but its max was HSDPA:9 (HSDPA:8 in JB).
Other phone such as Photon Q didn't have problem in connecting with HSPA+:15
Do I have to manually enable something? I believe this phone's potential is better than this
My carrier is using 2100MHz band, and my baseband ROM is a new one.
Is this info relevant : ?

If your carrier is using the 2100MHz frequency, this phone should have no problem using HSPA+ with it. When I travel to China, I use a China Unicom SIM in my MT4GS which enables my phone to use their 2100MHz HSPA+ network without any problem. Back at home in US, I use T-Mobile SIM.

So, you are seeing H+ (HSPAP:15) right? All I can see with various ROMs are only 3G and H....
Do speed tests, symbols don't always mean what they say after all
Sent from my Nexus 4 using xda premium
just tested: only around 3Mbps whereas other hspa+ phone got 9Mbps...
Is there any hidden menu to tick this on?

The stock ROMs are configured by HTC/T-Mobile to display 4G when it has a HSPA+ connection. Other ROMs, however, will display 3G or H (depending on the ROM) for HSPA+. So, if you see 3G, H, or 4G, they are all HSPA+ connections. This phone operates data in the G (GPRS), E (2G or EDGE), and 4G/3G/H (HSPA+) modes. Depending on the carrier, it can perform up to 14Mbps HSPA+ but of course, you would rarely see that fast in the real world. It does not operate at the 21+ or 42+ levels of HSPA+.
I'm on a stock-based ROM (Miktouch), when I'm home on T-Mobile, I see 4G. Also, when I'm in China and connected to China Unicom, I see 4G.
I've never seen "H" on this phone, it always shown 3G or 4G (using stock ROM, just de-junked and rooted by myself)
IIRC speed test results, I had best down speed exceeding 14+Mbps on Wind in Vancouver and Toronto areas, but in US it almost always was 3G only (but then I was usually outside any large cities).

Thanks for the input, if you are using non-stock rom, still would you let me know what the following says in the most normal case:
setting - phone - status - mobile network type.
In my case, it's HSDPA:9, which seems obviously non-HSPA. Other phone shows HSPA+:15 or HSPAP:15.
Am I missing something, or HSDPA:9 can be also considered as a decent HSPA+ ?
I'm kinda downshifting toward MT4GS recently as I love its small form factor, but somewhat at a loss due to this limitation, thanks.
I think we all know that the chipset is capable of running 4G speeds, as both the models (3G and 4G) have the same chipset. Now, the Nexus 4 had a 4G hack wherein the device was able to run on LTE! Now, my question is, cant we hack the Moto 3G to give us LTE speeds?

Firstly this belongs in the Q/A section.
Now about your question, I don't it's possible since the two devices have a different chip set. The 4G variant must be having the 4G modem and the required files to make 4G connection possible. But, I can be wrong also.

from my very basic understanding the normal moto g doesn't posses the modem or radios for it.. other wise someone would had flashed it by now, like the guy before me.. I can be very wrong.

learned this the hard way, but it seems that moto g LTE uses a higher version chipset than ours, even though both are snapdragon 400. We dont have the modem and also.. no gyro.

That's just wrong. The normal Moto G features a MSM 8226 processor whereas the Moto G LTE uses an MSM 8926. The 8226 doesn't have an LTE modem.

Simple Answer: NO
Normal MotoG uses MSM8626 which is similar to 4G enabled MSM8926, but the fuse is blown during manufacturing disables the 4G LTE and makes it 3G only.
There is no way you could enable the LTE with Qualcom blows the FUSE.
MSM8926 -> 4G fuse blown -> MSM8626
1 more. you need 4G antenna tranciever Chip to get proper signal for the Modem which is not present in Moto G
