We are leaving the country the day our contract with AT&T expires. They will not unlock our phones prior to that date. I was planning on calling AT&T from Europe the day after our contract expires to unlock the phone, but we won't have access to iTunes. I've seen conflicting information on whether or not you really need to do a restore to unlock. Some people said you just need access to wi-fi to access Apple's authentication servers after you insert a foreign SIM. Can anyone confirm I should be able to use a foreign SIM after the unlock is processed by Apple without needing to connect to iTunes? I assume Plan B would be to do an iCloud Restore, but I'd prefer to not mess with a restore when we're away. Thanks!
