As of right now (Nov. 20, 2011) Funambol no longer supports Thunderbird, and BirdieSync costs 20 euros for the desktop version (some of us don't use our contact lists for commercial purposes so that's a little steep).
Zindus supports Thunderbird but for some reason hasn't decided to enable it to sync to the iPhone.
you can not reverse the sync
You can sync your iPhone to the Nook app including your bookmarks and other pages.
Sync it to iTunes.
No
In iTunes, click on your Iphone and mark the box to sync addresses. At next sync it will sync. If you have a MobileMe subscription it can automatically sync over the air without user intervention.
You can’t install apps onto an iPhone from iTunes anymore. Apple removed app management from iTunes in newer versions. To get apps on your iPhone, open the App Store on the device, search for the app, and tap Get or the download button. If you previously downloaded apps with the same Apple ID, you can find them under App Store > your profile > Purchased. If you’re using an older version of iTunes that still supports apps, you may be able to sync them through iTunes, but for most users today, the App Store is the way to go.
Through iTunes on your PC or Mac. In there you sync it, with your iPhone.
no, the sync just transfer the apps you have downloaded to the computer
Plug your iPhone into your computer and open up iTunes. Once there go under the Tab > Devices, ****'s iphone. Click it and you will see Sync in a small box at the bottom right.
There are 2 possible ways of doing this. You can either sync your iPhone Notes with iTunes then sync your other iPhone or use iCloud in ios5 to transfer the notes. Hope this helps
