Resolve Data Issues in WP7

when wifi ON, turn cellular data off or try this :
//fix data wifi 3g issue
Anyone with data issues try:

Diagnosis > *#32489# > Back > Back (to Phone Control) > [7] Network Control > [1] GFC > [3] Setting Cancellation

Wait for it to say success, then reboot. This fixed all my data connection issues after applying this patch.
