That's now my favorite hack. I'm in an area that gets great 3g but like my tp2 sometimes it switches to Edge for no reason, this hack is perfect for me, and unlike my cdma tp2 switching it to wcdma only I don't miss any calls or texts.

In addition to this, if you're in a fringe 3G area and want to force 3G, you can dial *#*#4636#*#* from the dialer, go into Phone Information and scroll down and change 'WCDMA Preferred' to 'WCDMA Only'.

Some users of CyanogenMOD or other ROMs may notice that their upload speed while on H/3G is poor. You can try this tweak to see if it helps. You need to be rooted or have a custom ROM for this to work.

-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

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.
