treo 700 internet problem

[rip_jeff]

i have the treo 700w from verizion, but its flashed to cricket. i accidently erased somethings, hoping it would work better,lol. now when i try to use the internet it tells me that the address is not valid. check the address and try again? n my pic mail wont work unless i go to my google maps n connect it, then i can get pic mail, but the internet still says the samething? can anyone tell me what i did or help me get it fixed? thanx adam
