Texting

Hello,

My wife and I have iphones. After the recent update (6.01.2) I believe, she receives every text message I get now. When I send her a text, I get it back also. Where we messed up in the beginning was I used the same iTunes account for both of our phones and I think now it is coming back to bite us. Any suggestions on how to clean up this mess without losing my contacts, apps, groups, music, etc....???

Please help!!!

Thanks,

Nick
