Telstra have stated, via their Twitter presence, that the Froyo update for the HTC Desire will not be sent OTA (over the air), instead you will have to download it off the HTC AU website and update it yourself. Apparently the update is too big to send OTA, which is fair enough seeing as though the HTC Desire HD ROM is hitting 250MB+ and I don’t think Telstra would want thousands of those downloads happening on their network simultaneously. To those of you unsure of what this means, you won’t get a notification on your phone saying there is an update available.
So to get the update when it’s out, head over to HTC AU’s HTC Desire support page and keep checking for the ROM Update. Then to install it onto your device you’re going to need HTC Sync and then Bob’s your uncle. We’ll be sure to keep you informed as to when the update is available 🙂
