Ok, here are all the things I have tryed. iTunes used to work fine before I upgraded to version 7.4. Now, My iPhone will only charge when hooked to the cradle. I have uninstall, reinstalled older and newers versions of iTunes. I have even deleted the iTunes folders. I have did a system restore but still no luck. About 3 restores. Which it picks up the iPhone then when the activate screen pops up, the iPhone icon disappears. I contacted Apple about the problem but they were unable to replace my iPhone because it syncs fine on my other pc. I am able to sync my iPhone to my second pc with has none of my 30gbs of music and outlook contacts. Everytime I connect my iPhone to the cradle and open iTunes it freezes iTunes were I have to do a Ctrl,Alt, Delete everytime. I am getting pissed because I can't even listen to my music, save bookmarks, or anything. I don't want to reinstall my os. Thats just crazy. Can someone please help me with this problem? One more thing. I can open iTunes and play music fine if the iPhone is not connected. Even with the iPhone disconnect, if I go to the iPhone tab in prefen tab iTunes freezes. Even tired different usb ports.
