I need to wipe my curve. I have 50% free memory and yet my SMS msgs are self deleting at a rapid rate. I have no idea what's going on. Anyway, how do I back up only my address book? I basically have no messages left to back up anyway. I want to wipe everything else completely and start fresh. I do need my numbers, though. Thanks

Use Desktop Manager to backup your device. You can then restore just the Address Book if you choose.

You can also sync your address book to clients on your PC such as Outlook if you have it

If you are using a Mac, you can try Missing Sync. Another option is using Google Sync & wipe your system. I'm not that big of a fan to use Google Sync, yeah it worked but I had head aches so I had to reload Missing Sync.
