I bought a MobileMe in April, and I wanted to use it as my new Apple ID. Since it was its own entity right from the start, and I wasn't able to change my old email (also your ID) to my new MobileMe account email address, half of my apps are on my old account, and half are on my new one. Generally this wouldn't be an issue, however, it is. When it comes time for an app to update (one that I've purchased on my new ID), the App Store on my phone prompts me for my old ID. Obviously, since Apple can't differentiate the accounts, and it believes the accounts are separately owned, I get an error saying I can't update the app without buying it. I was able to redownload all of the apps that were free to my new ID, and they're set now. It's the purchased ones that are the trouble makers. If I were having this problem with just one app, it wouldn't be a problem. But we're looking at 47 apps I've PAID for here. Obviously I don't want to pay for them twice. Dealing with iTunes Support via email (since they aren't special enough to have their own phone line for some reason) is inconvenient, time consuming, and frustrating. Anyone know what the problem might be, or how I might fix it? Long story short, the App Store is prompting me for the login to the wrong account, and it's giving me an error saying I need to buy it. Thanks.
