My wife and I both have jailbroken AT&T iPhone 4s.
Mine is running iOS 4.1, modem firmware 02.10.04
My wife's is running iOS 4.2.1, modem firmware 03.10.01
I jailbroke them both using greenpois0n.
We are travelling to the UK for a few weeks this summer and would like to use our iPhone 4s there. We used to live there and still have accounts and SIM cards with one of the UK networks O2.
I'm slightly nervous at attempting to unlock the phones in case all doesn't go according to plan and things don't work the way they should.
From what I've discovered, it looks like ultrasn0w is the tool to use.
But looking at it in the Cydia store it says it's compatible with iPhone 4 baseband 01.59.00 (and other basebands for iPhone 3G/3GS).
Will this work on both our phones with their current configuration?
Or do I need to upgrade both phones to iOS 4.3.3, re-jailbreak (greenp0ison?) and then unlock (will I then have 01.59.00)
Hoping someone out there can help me.
Many thanks
