[darkmaniac7]

I have an alltel HTC Touch, and on accidently flashed to the new Sprint Rom then back to the new alltel one, Phone calls is fine, VM is fine, text and picture messaging is fine as well but if i try and get to the internet or GPS or google maps it says it cannot connect to #777 for an unknown reason please call alltel, also if i try and update roaming or activate via *228 it always says it failed to do so and has never done that in the past. any help would be greatly appreciated!
