Hello, My company have given us all iphone4's and they won't allow us to update to ios 5. I've plugged it into my mac at home hoping to transfer a few albums onto it but when i drag a song it just bounces back and doesn't transfer. If I check manually manage it says "the iphone "x" is synced with another itunes library" and asks to erase. We are not allowed to erase our phones as they are running some kind of profile and connect to our exchange server for mail calender. Is there a way around this? Or can I use a third party software solution to transfer from itunes or mac to my iphone? Any help would be much appreciated.
