I am having an issue updating apps on my iPhone. Whenever it says that an update is available, I clicked to download the update and an error message pops up (Error 1004) and the update doesn't download. Anyone had any experience with this? I first noticed this problem after I had to change my user account with iTunes, (changing from email address to another). I thought that might have something to do with it, but I am able to update the apps by going to the app store ON my iPhone, but can't do it on my computer. I recently bought an iMac and have moved everything from the pc over to the mac, and the problem still exists. I even erased my iPhone and deauthorized my old pc, and then authorized my account on my new iMac and still the problem exists. There is NOTHING on the apple support site about this issue, and a quick google search netted some results but none with a solution to the problem.
