BackOff: Speed Up iPhone Syncs by Turning off Auto-Backup (BE CAREFUL!)
In the early (first generation) days of the iPhone and iPod touch, a common complaint was that the device backup process took many minutes and that this mandatory backup process slowed down the overall sync process with iTunes. These days the backup process for me is noticeable but not unbearably long. But, if iPhone/iPod touch backup process that precedes device syncing is still too long for your, the Griffin blog has some advice for you…
Their advice is to download and use the free…
…utility that works on both Windows PCs and Macs. It disables the iTunes Auto-Backup feature to speed up the overall sync process.
WARNING: Be sure to make an iPhone/iPod touch backup before applying any firmware updates!
