My iPhone asks for a different account password when I try to update apps

You should remove any apps that were attached to the OLD apple ID on the phone. Thats why it is asking. Those apps are tied to the old ID, so you need that PASSWORD in order to update it. I would have set it up as a new phone(A) or delete those old apps and download what you want again(B). Cant update apps connected to another apple ID.

*Just make sure to in settings, store, that its your apple Id in there....

You either plug it into Itunes and Restore the device(summary tab) or go to settings, general, reset, all content and settings. It will restore the device, then guide you through the setup, like you just bought it. Then you can put your apple ID in etc....Dont worry if you bought anything, you can download again for free. If its under YOUR apple id.

I there, i have a brand new iphone 5 and did an icloud restore from my iphone 4 so it has exactly the same things on as my 4 did. Suddenly i am also getting asked for an apple id password, which i think belongs to a friend of mine, who has never even used my iphone 4. I've had the 5 less than 2 days and no one has touched my phone. I cannot imagine my friend downloaded any apps on my phone without me knowing on her id and even if she did, it would've been on the iphone 4 too.

It took almost 4 hours to restore from my icloud... do i really need to reset the whole phone and go through the process again?

Many thanks.

Thanks alot! That really helped, But how do I know which apps were downloaded on the first ID?

Yes, how can I know which apps were downloaded using the first ID? Is there an easy way to see this?
