Did a search but couldn't find anything exactly like this, so thanks in advance for any advice! A Norwegian friend currently in the US would like to buy a new iphone here (probably 5s) before returning home. He has an iphone 2G bought from ATT during a previous stay in the US. At that time, he had to jailbreak it once back in Norway in order for it to work w/ a Norwegian sim & to have a Norwegian language interface. It's running OS Ver 1.1.4 & the firmware is 04.04.05 G. He does have an Apple ID but has not set up or used his iCloud acct. Questions: (1) Does it matter which US carrier he buys the new iphone from? As I read this thread (http://forums.macrumors.com/showthread.php?t=1637205&highlight=iphone+5s+verizon+tmobile+att), it shouldn't matter greatly but wondered if anyone here has had experience. (2) Will replacing the US SIM with a Norwegian SIM restrict the phone to 2G/3G or will it work on all networks available to the specific SIM card? (3) Once he gets the phone, what is the best way to transfer contacts, etc. from the old phone to the new - via itunes or icloud? Will either or both work with a jailbroken phone as the "donor" phone? Thanks again for any advice you can provide.
