Phone wont turn on: Restore Option?

[CoachStall]

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!

You could try and download the 3.0 firmware hold shift restore if you are on windows or alt restore on a mac. You could use pwnage tool for mac to create a custom 3.1.2 firmware which should keep the baseband for your unlock. Then download untrasn0w from cydia. Or pwnage tool will unlock it for you.

Is it possible to jailbreak and unlock using 3.0 or do i have to use the latest OS jailbreak? Once i restore it i will be back to 2.2.1 or whatever.
