First I want to say I did run a search on this before hand but this keyword search isn't efficient and returns too many results for me to go through so sorry if this was covered. So i'm going on Xmas vacation to Europe. First overseas trip with my iphone. usually i just get a local sim and drop it in and i'm good to go. But not so easy with the iphone. So i just wanted to get some advice on the best way to deal with it before i go. I would love to unlock and use an overseas sim for the vacation and relock it if possible, but i don't really want to risk it getting bricked if that's too much trouble. Also i don't want data roaming charges at all. So info on how to deal with that would be great too. Thanks.
