So my sister and I share my iCloud/iTunes account. And we'll I updated to ios6. Don't know if she did but yesterday she was receiving the messages I had going with someone else. I did get a notification earlier that she was using FaceTime but didn't think much of it. Either way something happened where she was getting the messages that I was sending/receiving. I have a 3GS running ios6. My sis has an iPhone 4. The person I was texting with has an iPhone 4. Somehow the devices linked n she got the texts too. What the hell happened?
