As soon as Google unveiled Android 2.2 (codename Froyo), we probably all began to wonder which devices would be getting the upgrade. AndroidCentral.com reached out to HTC with this very question. HTC responded that most devices released in 2010 will get the update. And HTC even gave a rough timeframe for the update:
[…] 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.
We’ll have to wait a bit longer to see if any older HTC devices also get the update.
Update: You can scratch at least one older device from the list. During Google I/O Android Fireside chat, it was confirmed that the venerable G1 would not get the update as there is not sufficient memory for the new OS.
