When I try to Update All In the App Store Icon or purchase an App from an outside source I get a Dialogue Box telling me that ANY APP I ALREADY HAVE ON MY PHONE was purchased in the MEXICAN STORE (??????) and that in order to purchase new Apps or update current ones I must SWITCH TO THE US APP STORE. (It does not tell me how to do this)! I have never BEEN to MEXICO; neither had my phone! None of the Apps are in Spanish. I am it's only user. What is going on? How can I fix it? I called Apple (in New Delhi - they had no idea but wanted more than the phone was worth to fix it)! Wassup???
