So you just bought the Android 2.1-powered Droid Incredible, or locked in a pre-order for the HTC EVO 4G.. and now Google’s gone and announced Android 2.2. Great.

Don’t fret; if your phone started shipping in 2010 (read: the Droid Incredible, myTouch Slide, EVO 4G, Desire), it’ll almost certainly get the upgrade treatment, according to HTC.

The gents over at AndroidCentral reached out to HTC for comment, and got the following back:

[...] if your phone was launched this year, we will most likely offer an upgrade for it to the Froyo version. This includes popular models like the Desire and Droid Incredible as well as hotly anticipated phones like the Evo 4G, MyTouch slide and upcoming models. We will announce a full list of phones and dates once we are closer to launching the upgrades. We are working closely with Google and our other partners to ensure we have the earliest access to everything we need to provide a complete and solid Sense experience on Froyo. We expect to release all updates in the second half of this year but can’t be more specific yet.

Of course, that leaves plenty of handsets unspoken for. While it’s reasonable to think that HTC might eventually stop supporting some older handsets, what about those that are just outside of 2009? The Droid Eris was released in November of 2009 — will it get to ride the train to upgradeville with all of its friends? As usual, we’ll have to wait and see.

The best part of all of it: the bit about them expecting “to release all updates in the second half of this year”. Sure, it’s not as specific as the update-hounds might want — but considering that the second half of this year begins in just a little over a month, it could be a whole lot worse.

Well, that was one wild journey. After a dozen or so false starts and a seemingly endless gaggle of leaked memos making promises that couldn’t be kept, Android 2.1 is now officially (really!) available for the Sprint Samsung Moment. Still no word on the update for the Sprint Hero. You hear that sound? Thats the sound of a million Hero owners collectively grinding their teeth.

The good news for Moment owners doesn’t come without caveats, though.

It’s not an over-the-air update, so there’s a bit of manual labor involved. Additionally, this update will wipe everything you’ve got on your device. Before partaking, make sure to back up all your apps, ringtones, pictures of your cats in people clothing, and any other crucial goodies you might have laying around. Text messages can’t be backed up, and aren’t synced to the cloud — so if you’ve got a text you like to turn to when the nights get cold and lonely, make sure to forward it to email or something.
