I'm new to the whole developer community. Hopefully this question is in the right place I've downloaded iTunes 10.5 beta and iOS 5 beta 3. I've yet to install either for these concerns: I just want to try iOS 5 on my CDMA iPad 2 not on mine or my wife's iPhones running iOS 4.3.3. Will our 4.3.3 iPhones sync normally with iTunes 10.5 beta? Also, we stream a lot of movies from iTunes to our AppleTV gen 2. I've read that streaming from iTunes 10.5 beta to 2nd gen appletv's is broken. Since my wife would shoot me, is there a way to install the iTunes beta on a different user profile for testing purposes and not screw up my version of iTunes 10.3.1 on my personal user profile? That way I could sync the iPad with the iTunes on a second profile without any crazy bugs messing up our normal everyday use. If/when I am done with iOS 5 could I then just resync my iPad with the iTunes on my personal profile and restore from a previous backup?
