Fellow HTC One users…I know you are anxious for some Android 4.3, but it looks like the developer edition is going to receive an update before the regular HTC One this week. Jason Mackenzie dropped this news yesterday, with no mention of certain carrier variants that will receive the Android 4.3 update. He did mention, however, that only US developer HTC Ones will receive this update this week, and that Canada will start receiving it next month.
So if you have a developer edition HTC One, be on the lookout for your update. You normal HTC One users will have to wait just a little bit longer. HTC is working hard on trying to get this update out to you, but will require a bit of patience.
