Hi Guys, I have a Verizon iPhone 4 jailbroke on 4.2.8 via pwnage tool. I wanted to let the battery die to fully charge back up to calibrate the battery (I know this may not do anything). When the phone came back on after I plugged in the charger my carrier logo was gone and I have no 3G service. Any thoughts or help on this would be appreciated. I know I may be in for a restore and rejailbreak, but wanted to see if this happened to anyone else. Thanks Edit: Wanted to add, I tried syncing with iTunes because maybe a carrier update would fix it, but iTunes came back with "Error itunes couldn't search for carrier update for unknow reason (error 1631).
