Android 2.2 (FroYo, short for "Frozen Yogurt") was released over the Summer 2010, however not all of the devices that will get this update have received it yet. Each manufacturer and carrier needs to add their custom modifications before it can be officially released.
This community wiki will list all of the known and rumored dates for devices. If you have an update make sure to follow the format that's been established, and the following guidelines:
1. Keep phones in alphabetical order listing the manufacturer and model
2. Specify if the date is confirmed or rumored and link to the source
3. If there is an unofficial release, link to the site where it can be downloaded
If you don't have a high enough reputation score to edit the wiki (currently 100), leave your suggestion in a comment or answer and someone will update the list.
