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:
- Keep phones in alphabetical order listing the manufacturer and model
- Specify if the date is confirmed or rumored and link to the source
- If there is an unofficial release, link to the site where it can be downloaded
- If a new update comes out (e.g. 2.3.5 over 2.3.4), link to the new and don't keep the old information
Note that devices that do not meet Google's Compatibility Definition will not receive a Google-sanctioned update. In the case of the major manufacturers and many others, that means they won't release an update at all since Google's certification is important to their business.
