Hi, I have an iPhone 4, running iOS 5, with about a year left on my contract with AT&T. I'm moving to Vienna, Austria in about 8 months for at least 2 years. Are there any ways for me to be able to unlock my phone to be able to use local carriers? I've looked online about jailbreaking, but I've seen various things that say that my firmware (04.11.08) won't work for jailbreaking. I don't know much about that - any help? Thanks!
