SMSBackup : easiest way to backup your SMS on Windows Phone
SMSBackup is a homebrew tool for Windows Phone that offers an easy and quick method to backup SMS on your device. The app is available for free but you need to have an interop unlocked device to run it. According to the developer first-generation interop-unlocked HTC, Samsung phones and fully-unlocked phones can run it ( If you have a Nokia you could try interop unlock ) . I have successfully run it on my Omnia 7 and the app does backup my SMS messages .. NOTE : I have not tried to restore em back .. I will try that on my next ROM flash. The app offers users the ability to back up to the device ( to the isolated store ) or external backup to your skydrive account.
NOTE : trying homebrew apps always has risk associated with it so you are on your own if you choose to unlock your phone / try these homebrew apps.
The XML is human readable , you can open it up via a text editor and you will see your messages in there. This can be quite handy if you are switching over to a new device or if you are planning to flash a new ROM.
BTW that £900,000.00 is mine don’t even try to claim it ;)
