Running 2 Apple ID's from the same PC Both my husband and I have an iPhone 4. When my husband tries to use his ID on his phone mine will pop up and he can't change it. When he goes into his settings his ID is there. This only started when I plugged my phone into the PC. 

Can 2 ID's be run from the same PC?
Based on an incomplete understanding of the problem, I think you want to click on the "Store" section of your Settings app on the iPhone. From Store, you can click on the Apple ID and then choose "Sign Out." You will then be able to "Sign In" as a different user.
