Xperia X10a 2.1: backup and restore blocked

Hello, I recently got an X10a (a month ago). However, a software update became available and I was prompt to download the back up and restore app from sony (


When I did this, the phone blocks me from running the app:


Install Blocked: For security reasons, your phone is set to block installation of applications not sourced in Android Market..


The only button available for me to press is "OK" - there is NO "Cancel" or "Settings" button as there should be....


Does AT&T have a back up app that I can download that is NOT blocked?!


firmware version 1.6

baseband verison 1.1.32

kernel version 2.6.29-rel

build number R2CA016

You have to get it through the market Place.

On the phone go to Market Place and serach for x10backup (no spaces).
