Adobe released Flash Lite 2.1 (now free to download) for the following mobile platforms a few days ago:
Nokia Symbian S60 v3.0
Nokia Symbian S60 v2.0 FP2
Nokia Symbian S60 v2.0 FP3
Microsoft Windows Mobile 5.0
Did I mention these are free and do not require an IMEI number locked to the phone?
Old news but worth mentioning: Flash Lite 2.1 was released for BREW some time ago. Also, Flash Player 7 for Pocket PC is still available.
For developers: Make sure you download the Flash Lite 2.1 updater for Flash Professional 8, and get all new device profiles.
More info can be found at the Adobe Mobile & Devices Developer Center.
