How to unlock iPhone 1.1.2 or 1.13 OTB
Written by Mike   
Friday, 08 February 2008

Everyone is dying to get a hold of this new gadget. I must admit, I joined the iPhone wagon. Nothing wrong being on the iPhone wagon because the price you pay ($399 USD 8GB Model or $499 16GB model) and the features you get with it is a killer deal.

I've been following the iPhone unlock threads. To be honest I was pretty intimidated by the process which made me hesitate from buying one and unlocking it myself. That quickly changed after unlocking 5 iPhones I can pretty much say I am confident in unlocking the next one. In fact, I'll teach you how and explain every little step so you can do it yourself and brag to all your friends that you're iPhone unlocking god... not really.

iPhone unlocking Requirements:

  • iPhone with firmware 1.1.2 / 1.1.3 OTB

will I also be able to add custom ring tones and upload NES rom games?
Mikey (24.86.132.xxx) 2008-02-27 23:49:34

you can do whatever you like to the phone. the phone will be fully
unlocked/jailbroken/ activated. installing NES will be found under installer..
you just need to add site sources that lets you download them.

Thanks! However, other websites also have a final step of running a jailbreak
program after you have upgraded to 1.1.2. Is this true, must I run another
jailbreak after I have used iTunes to to upgrade to 1.1.2?
