I've got an AT&T iPhone 4 and will be moving to Switzerland for a year later this month. I have a few questions about AT&T ETF and using the iP4 in Europe: 1. I've heard that I can be released from the AT&T ETF if moving internationally. Is there a preferred method or contact to get this done with the minimum amount of pain? 2. What is the safest/easiest way to unlock an iP4 for use in Switzerland/Europe? I am currently not jailbroken and have never done so before, so an easy step-by-step would be appreciated (searched the forums, but found most explanations about basebands, etc to be complicated) 3. Will I have full functionality in Switzerland with an unlocked AT&T iP4? 4. Will AT&T know when I unlock the phone (and even if so, do they care?)? I may be going back and forth between the US & Europe for a bit before the final move and may be switching SIMs, etc. 5. Anyone that has familiarity with the Swiss networks (Swisscom, Orange, Sunrise): any feedback on network quality/speed as well as rates (including roaming in Europe) would be appreciated. I know that many of these questions have been answered to a certain degree in other threads, but I could not find clear answers for all of them. Appreciate your input!
