So here's one for ya.
I'm signed in to the Apple store with the correct ID. I can verify this by going into settings-->itunes-->etc... Also by going into the itunes app itself and scrolling to the bottom of the screen.
Here's the problem. When I go into the app store and try updating apps that I'm absolutely certain I purchased with the ID that i'm signed in with (my ID), it asks for the password to my wife's apple ID. I could just enter her password and all is fine and dandy EXCEPT it would make me pay for the app again since it was not originally purchased under her ID.
It seems to me that somewhere in the programming some master file that lists what ID the apps should be associated with became corrupted and now shows the wrong ID. Then only way I've found around this is to update the apps in iTunes on my computer first then sync my phone. Seems to not have any problem doing it that way.
This problem seems to be isolated to my iPhone 4s as I have an iPad 1st gen signed into my apple ID and updates the same apps without any problem on the device itself. Any smart programmers out there think they could write an executable program to fix the prob?
