I've seen screenshots of Captivates homescreens from you peoples showing an H instead of just 3G. May I ask how you enabled this? Thanks in advance!

HSDPA and 3G are the same thing (i'm pretty sure)
or more technically speaking, HSDPA is one half of 3G, with HSUPA being the other half (HSDPA=download, HSUPA=upload)...
can anybody correct me if i'm wrong?
You're correct. AT&T requires all its 3G phone to display 3G instead of any other icon. Often times, ppl find ways to replace it with the native 3G icon, H, which is widely used by rest of the world. But that makes no difference in actual connection speed.

this is correct. when referring to both of them together they are commonly called just HSPA.

"3G" is the common short abbreviation for UMTS. HSDPA is an update to UMTS that gives faster download speeds (a version is widely deployed on AT&T). HSUPA is a protocol upgrade that enables faster upload speeds (installing HSUPA equipment borked upload speed on AT&T recently). Combining the two is called HSPA. HSPA+ is an update to HSPA that's even faster. T-Mobile is planning on rolling this out. LTE (AT&T's 4G pathway) is totally unrelated to HSPA.
Thanks for your replies! I appreciate the schooling

This is the correct post.
Also, I'm certain AT&T doesn't disallow the H icon because I've seen screenshots of the Captivate with that icon.
However, at the same time, I have a -51 dBm signal and no HSUPA which I know I should be able to get here because my iPhone 4 got it. Something is going on, but I'm not sure what yet.
Edit: Nevermind, it sounds like I'm wrong. In the manual there's no mention of an H icon. There's also no mention of HSUPA. I think we just got screwed by AT&T. What a surprise.

I'm pretty sure AT&T does disallow use of the H icon. They did on my Fuze. The reason is that there's ALWAYS confusion when people don't have a good operational knowledge of the protocol names. There's always someone on the EnergyROM or Cyanogenmod threads asking why "only" H comes up when they expect 3G.
Anyway, I have an AT&T band Nexus One as well as a Captivate. The N1 is definitely HSUPA compatible. I just tried speedtest.net a few times and got an average of 2.5M down and 175k up (5 runs no run over 256k) in midtown Manhattan. On my Captivate I'm getting ~4M down and 200k up. Upload speeds are about the same, probably limited by AT&T's current (under) capability.
I don't have access to an iPhone 4, but if you do, could you do a few runs on the speedtest.net app on both devices from the same location and let us know the results? At this point, I'm pretty convinced it's the HSUPA equipment screw-up at AT&T not lack of HSUPA on the phone.

That's what I was saying. My iPhone 4 got HSUPA here with no issue at all. When everyone else's HSUPA had issues, I still had no problem at all. So unless HSUPA decided to die in my area the day I returned my iPhone 4, I don't think the Captivate has it.

When did you return it? The iPhone 4 was released on June 24 and the AT&T HSUPA issue cropped up around July 6th or so. That's when my Nexus went from over ~1M up to ~200k up. If you gave it up after July 6, what sort of upload speeds were you getting? What sort of speeds are you getting now on the Captivate? Not trying to grill you or anything, I'm genuinely curious.
I've looked all over the internet and cant find any place that confirms or denies that this phone is HSUPA compatible.
I did a speed test this morning on my way to work and got 2457 down and only 170 up. Thats a pathetic upload speed. I'm guessing from that speed that the phone is not HSUPA. But AT&T has been having problems with their HSUPA software since the iphone4 launched and maybe my low upload speeds are because of that?
With that low of an upload speed it'll take forever to upload photos in MMS or to facebook and would take a lifetime to upload a 720p video to youtube.
i can tell you that the upload is pathetic compared to my iPhone 4 in the same apartment. Download speeds are comparable, but upload seems to cap out around 150k.
On my HSUPA iphone the uploads cap around 1.1mb

It doesn't have HSUPA. Or if it does, it's not turned on. Let us only hope that the radio supports it and an update will turn it on.
From your phone type *#0228# and it should show that your connected to hsdpa or umts.

No, on the box it just says quad band GSM and lists the bands and then it says tri band umts and lists the bands. It doesnt mention hsdpa or hsupa on the box.
Plus, with AT&T's network crapping out on hsupa right after the iphone4 launched who knows what the problem is, possibly the phone has it but the network is broken.
Really, with as much as I hate AT&T, I'm thinking they are crippling upload speeds in congested areas because certain parts of the country are still getting hsupa speeds on their iphone4's.

I'm a noob to Android but my screen reads Network HSDPA
RSSI: SIgnalStrength 16-1-1-1-1-1-1-1 gsm
The first number changer between 16 and 8 others numbers stay 1
FWIW First number went to as low as 4
Speed test was 3057 down 394 upload
HSUPA is currently tuned off in many (most?) AT&T markets right now until they address a so called software issue.
Nobody ready about this?
I've read of someone on their captivate getting over 1mbit, and that is obviously HSUPA, but I don't think he was in an area where the lucent equipment is in use that is causing the AT&T upload issue.
Ooops, I guess someone pointed this out...

Samsung US website does not show this on a feature Captivate or any other Galaxy phone
I haven't seen anyone who has gotten HSUPA speeds on a Captivate. On a Galaxy S, yes, but not a Captivate. HSUPA works fine in my market, and always worked fine on my iPhone, but never on my Captivate. It just doesn't look like it has HSUPA, or at least it's not enabled. Hopefully it's something that can be turned on later, but I wouldn't be surprised if it never is. If this was an AT&T decision, then I'm very disappointed, but not entirely surprised.

I just installed Atinm's Kernel w/HSUPA on my captivate and here are my before and after speeds.
1402 down 247 up
2142 down 1662 up
I was already running cognition 2.1.5 with the voodoo only kernel.
In a letter responding to a complaint I filed with FCC the AT&T representative stated
"In regards to the issues with HSUPA speed; HSUPA is disabled from all AT&T handsets and is currently only available on our aircards. We also do not market the Samsung Captivate as a HSUPA capable device.
I am sorry for any inconvenience this issue may have caused you."
She didn't deny that it, or their network were capable because then she would have to admit to the problems they are having with bandwidth volumes that servers can't keep up with. A similar problem that U-Verse is developing/creating for their formerly content DSL subsribers in my area.

All handsets but the iPhone 4. At least its a semi-honest answer.
HSUPA works on 2.1 (with HSUPA hacked modem file).
i'm not sure i should downgrade back to 2.1 , i really miss the HSUPA on froyo 2.2

Install Cognition Beta 8.
Or an i9000 ROM.
Both are in the Android Development forum.
This is old news.
Several who complained to FCC about this back in August got very similar responses from AT&T.
I received a case regarding your concerns with the data connection speed for your Samsung Captivate.
In regards to the issues with HSUPA speed; HSUPA is disabled from all AT&T handsets and is currently only available on our aircards. We also do not market the Samsung Captivate as a HSUPA capable device.
Did they enable it only in the iPhone to offset disappointed followers?
Several custom ROM available here to you enable this feature with great results.
I look at phone status it says hsdpa some times and hspa the other half which I'm assuming means hsdpa and hsupa? Not sure if this means anything.

Can you provide a screenshot of when this happens and run a speedtest and tell us your results? This would be very helpful as many of us, at least myself, do not believe I have HSUPA enabled.
mine is sitting on HSDPA right now... while i'm sitting in bed.
HSUPA is either disabled in firmware or AT&T is actively restict the upload speed for Captivate. Anyway I have never seen my upload speed higher than 300 to 400 kbps. If you have HDUPA enabled, you should see 1mbps upload speed as my friend's iPhone4 can consistently demostrate.
HSDPA is for download speed. If you get download speed over 500kbps, you have HSDPA. Mine can often get to 1 to 3 mbps.

Yes, HSPA is NOT HSUPA.

How can you check what your download speeds are? What app do I use or is it already in the phone?

I like Speedtest from the market. Its pretty solid. or you can go to m.dslreports.com/speedtest from the browser (use the iphone speedtest there).
Well hspa is high speed packet access which can refer to up and down link, how do I screen cap. Or do I need an app for that

you have to root the phone before you can screen cap.
There is really no need to post any screen cap. Download the speedtest app from market and report your results.
The Cap has HSDPA, but not HSUPA. Do some looking on this forum you'll see where others have analyzed the modem.bin file from the Captivate vs the one from the Vibrant. All of the HSUPA stuff has been removed from the Captivate version. You can get HSUPA on the phone by flashing the I9000 modem file to the Captivate. Data works great, people were regularly getting 1.2Mbps upload. But they had no voice out on telephone calls so it was worthless. Same with the Vibrant modem file. Also, those only supported 1900MHz, not 850/1900 MHz, so if you are in an area where you have 850MHz 3G it wouldnt work at all.
Its been clearly established there is no HSUPA on the phone, AT&T has completely removed it from the software (although the hardware does support it). The last hope is when Rogers Canada gets their version of the Captivate, if they leave HSUPA enabled, that modem.bin file may work on our AT&T Captivates properly since they use an extremely similar network and the its a Captivate, not a Vibrant or I9000. When I said HSPA is NOT HSUPA I meant that just because you see HSPA in one of the menu settings in the phone that is not HSUPA.
Have an Inspire and have read that it can be 'rooted' to get hspa+ speeds? There is hspa+ in my area but my Inspire doesn't seem to get speeds.

Concerning cell data speeds, rooted ROMs are no faster than the current stock ROM. You're probably seeing the same slowdowns that a lot of us in H+ areas experience from time to time - the problem is the network, not the phone or ROM.

Agreed. Ever since att has enabled hspa+ capabilities, I think back in April, the inspire has been capable of the best speeds the network has to offer. Stock Rom and rooted roms both have the necessary "build.prop" to run hspa+

I have a Samsung Blaze (originally for use with T-Mobile) and would like to use it on the AT&T network. It is already unlocked. I can make/receive calls and texts with my AT&T sim in the phone.
On AT&T's network, my fastest speed test so far is around 7 Mbps down and around 1.2 Mbps up.
I have been reading for a while now in these forums about how it is possible to flash a different software modem into various Samsung phones in order to get better functionality or data speeds while using these phones.
If I want to get faster download speeds or even functionality with AT&T's LTE network, then is it as simple as flashing a new modem, perhaps the Skyrocket modem? Or am I limited by the hardware itself?
Is flashing a new modem into a Blaze 4G even necessary since I keep reading about how people are solving their slow bandwidth issues by flashing a Blaze modem into their phones?
It would be nice if I can avoid buying an AT&T device, but if I have to do that, are there any recommendations from anyone?
