Definitely a awesome hack. I agree its my favorite also.

If you don't want to force HSDPA (WCDMA), you can also try setting this to GSM Auto PRL, which some say is improving their battery life. You still get switching between HSDPA and Edge like you would with WCDMA Preferred, but supposedly better battery life.

-You need to have USB Debugging on.

-You need AndroidSDK installed (or a way to use adb).

-adb pull /system/build.prop build.prop

-Edit that file with something like Notepad++

-Search for (or add) ro.ril.hsxpa=2 or ro.ril.hsxpa=1 (some people report better results with 2)

-You can also check ro.ril.gprsclass=12 (by default it may be 10, so you can try 12)

-Save the file

-adb remount

-adb push build.prop /system/build.prop

-Reboot the phone (you may have to twice)

INFO:
ro.ril.hsxpa=0 - UMTS r99
ro.ril.hsxpa=1 - HSDPA
ro.ril.hsxpa=2 - HSDPA/HSUPA

GPRS Class----Max. data transfer speed
Class 2--------8 - 12 kbps upload / 16 - 24 kbps download
Class 4--------8 - 12 kbps upload / 24 - 36 kbps download
Class 6--------24 - 36 kbps upload / 24 - 36 kbps download
Class 8--------8 - 12 kbps upload / 32 - 40 kbps download
Class 10-------16 - 24 kbps upload / 32 - 48 kbps download
Class 12-------32 - 48 kbps upload / 32 - 48 kbps download

am I using the cmd window with this? are these commands? The adb pull?

Yeah, if you use the ADB method, you connect your phone to your PC and use the AndroidSDK. once connected, use CMD and try 'adb devices' and make sure your's is listed, then continue with the walkthrough.

If you have RootExplorer installed you can use that too. Browse to the file and mount as R/W, then long press and open in text editor. Use the trackball to scroll through the file to find those lines and change them.

Awesome thanks, root explorer worked like a champ.
