iPhone 3G OS 3.0 jailbroken and unlocked Phone wont charge, or turn on. I get the silver apple, but it shuts off after that. Reset method of home key and power yeild same result. itunes does not see phone. When i hold home key, the itunes logo and usb cable appear and i am able to get it on itunes, with option of restore to factory settings. Several questions and concerns: 1) this will wipe all data and contacts? 2) my OS will return to 2.2 something i belive. Can i still download OS 3.0 and the firmware to needed? Phone must be unlocked/jailbroken for use on my carrier. 3) where can i download above files? Any help is appreciated!
