After its flip-flop on whether the HTC Desire would get ugpraded to Android 2.3 or not, HTC now expects to have the update out by the end of the month. According to the latest Facebook update:
Hi everyone. We have more news about our build of Gingerbread for Desire. Our testing has gone well so we will begin rolling out the update by the end of July! Thank you again for your support!
It still remains to be seen how quickly TELUS will then approve the update for its customers.
