I reinstalled my OS and iTunes on my computer a couple months ago. I forgot about iTunes before I erased everything. Luckily I hadn't bought any songs/movies directly on the phone so I didn't have to worry about getting those off of my phone back into iTunes, but when I plugged it in, it said something about my phone/account already being linked to another computer and I think that I could only have up to 5. So I now only have 3 left even though the 2 in use are the same computer. Is there anyway to fix that? Also does anyone have a link to a good walk through on how to backup iTunes before re-installing so I don't mess it up next time?
