    Question official unlocked 3G, 3.1.2jb, bb 05.12.01 got no Phone Signal?

    Hi guys,

    I got a JBed iPhone 3G 3.1.2 with Baseband 05.12.01 that has no signal( searching always....) . And I JB this phone with Blackra1n or Redsn0w. I have tried reboot my signal component via terminal,
    also BBUpdaterExtreme following this post: MDM DZ: Downgrade iPhone firmware 3.1.3 to 3.1.2

    I know it may be impossible to downgrade the BB, my bootloader is not support by Fuzzyband also...
    however, My iPhone is bought from Hong Kong, unlocked officially. And how can I restore it to a normal iPhone without JB? Just wanna use it first....

    Thanks for every bump and answer!

    if it is really officially unlocked, then you simply need to restore it in iTunes, put in a valid SIM card from any carrier and let iTunes unlock and activate the phone for you.

    Only after you do this should you jailbreak. (with redsn0w iClarified - iPhone - How to Jailbreak Your iPhone 3G on OS 3.1.2 Using RedSn0w (Windows) )
