So I've been in Sweden for a week out of 6 weeks so far. And my phone hadn't been updated for a while, so while I was bored I updated it. It was on like 5.0.1 or whatever that last update was before 5.1. And I had no issues sending or receiving iMessages in airplane mode (I'm from the US so I don't want to incur fees here, so I just text via iMessage). So after the update, all seems well until I go to my internship the next day. Change wifi networks suddenly iMessage doesn't work any more. Restart it, soft reset, plug it in to the comp blah blah blah, doesn't fix it. Take it out of airplane mode, suddenly it works. Then put it back in airplane mode, and it's fine. Then I go back to my apartment here again. BOOM same problem as earlier. So this has been going on now for 3 days, and I have no idea why. If I look at iMessage when I'm in airplane mode, it says waiting for activation... But I connect via cell network and then put it in airplane mode, it activates and does it all fine. But if I turn iMessage off after that (this I discovered while testing for reasons as to why it's not working), BOOM it goes away again.. I really don't get it... Any help would be greatly appreciated. Thanks guys.
