i bought a phone on ebay and didnt know it wasnt already programmed for cricket until after i had it activated... So i had a phone number and phone line but it would only give a busy signal. I was told i should try to reflash the phone before i send it back to the seller. When i took the phone into the cricket store they converted the dec number to get ESN number to activate the phone line... After flashing the phone do i have to call cricket to reactivate it?
