help me unlock week 29 upgraded to 1.1.2
I have acquired a week 29 activated, locked, not jailbroken iphone that has been upgraded to 1.1.2. This phone was bought in the US in early September.
I wish to unlock it to use outside the US. I would appreciate it if you could help me with some questions that I have. I have another unlocked week 44 that I jailbroke using jailbreakme.com and unlocked using anysim 1.1, so I have some (albeit little) experience.
My questions are:
How do I find out which firmware version should I downgrade it to in order to unlock it, or can I downgrade it to 1.1.1 and unlock using jailbreakme and anysim 1.1?
Your help on this matter will be greatly appreciated.
