Hi,
Just wanted to clear up some things, since there wasn't a clear answer to if these would work with unlocked iPhones..
I have a 2G 8GB iPhone running a 2.0.2 that has been pwnd, unlocked and jailbroken from WinPwn.
I needed 2.1 for some apps from the App Store, and I like to keep my iPhone stock (no need for flashy mods) so I downloaded
iPhone-2G-2.1-custom-activate-nobootlogos.ipsw
from
The first post (iPhone.greatness.tx.com
I backed up my iPhone, and did the Shift-Click restore method and chose the iPhone-2G-2.1-custom-activate-nobootlogos.ipsw file.
It restored, and BootNeutor showed up and it said it was already unlocked and didn't do anything to it.
My iPhone rebooted and went to the home screen, and had signal from T-Mobile (I'm in the US)
Just restored the backup and everything is in place.. My pics, WiFi settings, APN Settings, ect.. The only thing it didn't transfer was my apps from the App Store, Music and Ringtones..
Hopes this helps clear stuff up!
