Continuing on with the complaints about the long backup process every time you sync your iPhone, here is yet another little trick that should help to cut that time down a bit, and thankfully this suggestion will not involve turning off the backup process.
Thanks to a nice forum posting over on the HowardForums, you can now cut that sync time down and still be prepared should something unfortunate happen to your iPhone that forces you to have it replaced.
The process is simple and it involves turning off the ability to send diagnostic data to Apple.
With just a few easy steps you should be left with sync times that are much more manageable, of course this will not help if you add a bunch of new media or the first sync after you add some new apps, however regular or routine syncing should be much more pleasant.
After connecting your iPhone to your computer;
- 1. Uncheck the check mark from the “Automatically sync when this iPhone is connected” option in iTunes.
- 2. Unplug your iPhone and then plug it back in
- 3. Once iTunes launches again, right click on its name in the devices menu (on the left) and from menu choose “Reset Warnings”
- 4. Then click Sync in the bottom right hand corner
- 5. You will then receive a pop-up (see image below). Simply uncheck the “Do not ask me again” box
- 6. Now you can go back and re-apply the check to the “Automatically sync” option that you removed in Step #1

Brilliant tip! That should help a few people.

Sure, but don’t you think that providing Apple with diagnostic feedback enabled them to pinpoint bugs to address in the iPhone 2.0.1 firmware update?

Steps did not work with iPhone Firmware 2.0.1 and iTunes 7.7.1.11
Any other way to apply it?

Excellent post.
I run an iPhone 3.1.2 jailbroken latest iTunes software as of this date. Yesterday it took me all night with iPhone on itunes (haven"t synced since jailbreak) and it was still backing up. After following above steps backup completed within 10mins.
Thanks
