good day to you
i have an iphone 3gs
my iphone was on 3.01 firmware and was jailbroken and unlock
i tried to do reset iphone from the iphone general options but than the iphone got stuck on the apple logo
i'm not sure from what week is the iphone (i don't have the box) and i'm not sure if there is a cydia backup or something because i got it 3 days ago from someone
now i don't know what to do
i don't want to get stuck with iphone that can't be a phone or can't be jailbroken
is there something i can do?
the only thing i remember is that the modem starts with 04
i really need your help guys
thank

If you did a reset all device settings and erase content, then the iPhone did just that -- it reset all device settings and erased all content. By design, the device needs to be re-flashed with firmware after a content erase. If you have completed the full erase and do not have a 3.0.1, 3.1, or 3.1.2 SHSH on file, your only option at present is to restore the factory 3.1.3 OS onto the device, upgrading the baseband to a presently NOT unlockable version and upgrading the OS to a presently NOT jailbreakable version.

If you have any of the SHSH's on file, use the SHSH + Firmware Umbrella or Saurik's server to complete an upgrade to that firmware.
