i opened itunes and right before i connected my iphone4 to sync it, i accidentally clicked on something i don't know in itunes, and ended up in a section in itunes called "Downloads" and a question poped up on the screen. i don't remember the exact question, but it was something along the lines of "would you like itunes to check for..... to keep your purchases" i had to answer with "YES" or "NO" since i didn't understand, i just hit "Alt+F4" and the question disappeared. and i closed itunes, then opned again and synced my phone normally. i am a bit worried since i didn't understand the question and i am not sure if i answered YES or NO when i hit "Alt + F4" i just don't want it to have messed anything related to my phone settings or apps, or i will have any sort of conflict or error if i ever have to restore my phone. can someone advise?
