Windows 7: Iphone sync issues

I can't get my iPhone to properly sync with iTunes under Windows 7 RC 7127.

The iPhone is recognized by the system and its recognized by iTunes, but when I click on sync it starts with iPhone backup first and it gets about 3/4 of the way and just sits there. I can then cancel the sync on the iPhone and try again and get the same problem. So because it never backs up, it never syncs.

I had similar issues with Windows 7 RC 7100 and after I restarted the computer it worked. But with 7127 I can't get it to work at all.



Anyone else have any issues?

Not here...my iPhone 3G syncs fine with 7127 and now 7137. My only gripe is that it will not open iTunes and sync automatically when I plug the phone in...it used to in Vista...but not too much of a hassle to do it manually I guess.

I uninstalled and reinstalled iTunes and all Apple software. I tried again and got the same issue, but this time i got patient.

The first sync wants to do the backup. It took about half-hour to do it, but after that it finally synced. I hope backups don't take this long everytime. I see no options in the software to make it stop doing backups.

You really don't want to disable backups for the iPhone if you can help it. My first one was stolen and I think I'd still be trying to set up the replacement were it not for the backup.

You might try giving the phone a hard reset...press and hold both the menu and power buttons until the Apple logo reappears. Sometimes that helps with internal junk collection and may speed up your backup process.

The problem isn't Windows, it's the phone. I had the same one awhile ago when the iPhone 2.0 firmware came out. I tried to update and it would start a backup first but never finish. The only way I fixed it was to reset the iPhone. It's a pain and you'll have to give it a lot of time to restart and then to sync all your music back, but it should fix the problem. The biggest hassle is losing your contacts, so make sure you find a way to save those before resetting.

Have you noticed any problems with other USB operations?

Since installing Windows 7, anything I do via USB is painfully slow. This includes syncing my iPhone, transfering from a flash drive, etc.

I too have had problems, but I found a program called iPhone Backup Switch, that will disable/enable backup for iphone. I left my phone "backing up" overnight to have it still not completed. So try that.

My phone would start syncing fine, then after a few minutes would just get stuck. I tried reinstalling iTunes, restoring my phone and even left it syncing for 8 hours hoping it would eventually Finnish. All that , and no change. After trying different things, I discovered that if you deselect the picture syncing ( do not sync any photos to you phone) it syncs fine. Everything works as it should, music, video and apps etc.

My external HD fails part way into a backup (unknown device) and I just bought a brand new iTouch which fails (same thing) during a sync. The same HD worked flawlessly under Vista x64 (I have Windows 7, Intel quad core and 4G ram)
Tried my front USBs, back USBs etc....

That appeared to work for me also. I unchecked syncing my photos, and my iPhone backed up and synched normally.
