I got a new iPhone 3GS about a two months. I synced it up just fine, loaded up my music library and went app crazy with my credit card. My PC had an issue the other day, that required a fresh reinstallation of Windows. I reinstalled Windows (7 RC1) and iTunes. I hooked up my iPhone to the PC and authorized the computer with my iTunes account. Now, for some reason I can't sync anything. I can't add music. I can't add apps. iTunes doesn't even automatically back up my phone anymore. I thought that was what authorization was for? The weirdest part is I can't even PLAY my music through my PC, all my songs are grayed out and unusable. I can re-add my music if I have to, I don't want to, but I can. I don't want to resync my apps because I just bought some today while on my phone, so I don't have those backed up and will lose them if I re-sync the phone. I also don't want to lose any of my other info on the phone, but I'm fearing that I may have to reset the phone to get back full functionality. Of course, Apple is no help. No documentation on their site for anything similar to my problem and I can't even find a support email address anywhere on their site, which is absurd for a company of its stature. Has anyone dealt with anything similar to this? Is there a workaround? Thanks in advance.
