i wanna get a new 3g iphone unlocked, but still researching...i have a question, if i do an erase contents and settings for iphone, is the installed application gonna be removed? like Installer, remote, etc... or just the media files like music, photos, mail etc...? will it still remain unlocked and jailbreaked? coz i saw some video, and see that bootneuter is at the home screen. i guess that's an app use to unlock? what is the usage of bootneuter anyway...? please help me...thanks.
