It has eliminated another possibility then. I think there is some difference in the configurations for the SMS (in the baseband software as well?) besides baseband hardware difference. Well, if firmware update is available to your Telstra HTC Desire, you may give it another try. BTW, do you have access to a Rogers or Fido SIM card?
You have the good suggestion. But what version of Android the TELUS and Telstra Desire are running? Both have got the same build of Froyo? I wonder if it will bumped into problem with the restore if both variants of Desire are running on different build of Android. Not to mention, it requires root to use Titanium backup.
