Were you ever annoyed of iTunes always backup your iPhone every time you sync? If ever you got a 5Gb of songs on your iPhone and updated a single number on your Contacts then Sync it on iTunes to update your Address Book. iTunes always perform a backup of your iPhone. So you have to wait a long process of backup for a single modification done. Well that is over. This command will change a hidden setting in the iTunes preferences that will force it to skip the backup process. 1. Quit iTunes. 2. Open Terminal.app 3. Copy and paste this in, then hit return: defaults write com.apple.iTunes DeviceBackupsDisabled -bool true 4. Open iTunes 5. Plug in your iPhone (2.0 or 3G) and sync. It will take a few seconds, assuming you don't have a ton of music or podcasts. Changing the 'true' in step 3 to 'false' will re-enable the backup feature.
yep you can just click on the x icon when its backing up ang it'll just go on and sync. i wouldn't recommend the process above because "it will not back-up" your iPhone. Incase you might need it in the future..
