On Xperia X10, AT&T
This is quite frustrating...have been following the instructions in the user guide to the letter, I can download but can not install SE's Backup and Restore:
'Installing applications from unknown sources':
Mark the Unknown Sources checkbox. ---This Unknown Sources checkbox does not exist on mine---
In addition, after I download and click, I receive the 'Install Blocked' error message AND ---The only option to click is 'OK'; there is no setting button displayed on this error message---
Any help here will be appreciated, thank you!

The 'Unknown sources' box is certainly available on the software produced by Sony Ericsson, but I suspect that this is something that AT&T have tinkered with and removed from 'their' phones. I don't think that there is a lot you can do about it. I have seen various messages on here (largely in the thread about the update to 2.1 in the U.S.) about debranding the phone, but that would be at your risk, and it wouldn't be for me to recommend it...
