Hello, So I got an Iphone for christmas while I was visiting my mom. I got the Iphone, activated it, and used it while I was visiting her. I put on many apps while I was there, using one email account. When I got back home I finally plugged it into a computer, and I accidently used a different email account for the registration of the Iphone. I am assuming this is what is causing my problem. The SMS, Email, phone, contacts, everything pre installed on there is working just fine, but all the apps i downloaded work only sometimes on my phone. I don't know what is causing it, but here is what happens. I click on the app, it pops up like its initializing, then it just exits down to the home screen again. Please if anyone has any suggestions on how to fix this problem, it would be much appreciated.
