This is the new app that you see when you download the "back up and restore' apk file from this site through the browser of your phone, wifi or 3G.
Problem: There's no more back up and restore app from Android market after updating the firmware of Sony Xperia X10 to 2.1. How to read the file .sbf that was saved when the app "back up and restore" was used before updating the Android 1.6 to 2.1?

Steps:
1. Use "back up and restore" app on your phone, save to SD card.
2. Update the firmware of your phone through PC Companion, when you connect the phone to computer. (if you dont have the PC Companion installed,  this should be done first).
3. After installing the new firmware of your phone, connect the phone to wifi, and browse in Android market for back up and restore: nothing. Do this, on your browser, type http://www.elita-clan.com/downloads/backup_and_restore_v010935.apk. The phone will display "start downloading" while the browser will give an error message.
4. Check from your Downloads app, then install the "back up and restore" app. Give authority for the installation.
5. Now you can restore the .sbf file that you saved into the SD card and recover contacts, messages, missed calls, etc.
