I upgraded to Titanium Backup Pro today and re-flashed and rooted with 2.1 generic Brazil x10a using SEUS and z4root. I wanted to start over fresh and check some of the different settings people are using.
I wanted to check out the 3G(GPRS) vs H(HSPA) difference. Since the APN User ID ends in GPRS, I am wondering if we are limiting our speed by defining it. If you look in Settings > About phone > Status > Mobile network type > it says we are using H(HSPA). I used SpeedTest App and different APN settings see if I could find a difference.
I used the standard AT&T Cingular GPRS APN settings above, and ran 6 download/upload mpbs G speed tests. Then removed the User Name, Password, and MMS Port 80 from the APN settings hoping it would allow speed to increase, and ran 6 more download/upload speed tests to compare. Below are the two results.
Speed Test Name1: AT&T GPRS APN Test(download/upload) mbps
T1(1.46/1.01) T2(2.01/1.29) T3(2.20/0.89) T4(2.30/0.66) T5(1.42/0.65) T6(2.03/0.86)
Download Average 1.90 Mbps, Download high 2.30/low 1.42
Upload Average 0.89 Mbps, Upload high 1.29/low 0.65
The second test I ran with basically the same location settings, and I removed the speed settings.

Speed Test Name2: No User ID APN Test(download/upload) mbps

Name2: APN Download 2.59 Mbps Average = .69 Mbps or 27% faster (consistent +/- .07 mbps)
Name1: APN Upload 0.89 Mbps Average (Range +/- 27%)
Name2: APN Upload 1.27 Mbps Six in a row = .38 Mbps or 30% faster
**About 30% faster/100% Consistent**
