I started working on a FlashLite 2.x application to update Twitter status from phone. I have unlimited data-plan, so I can save money by not sending sms messages.
The application just updates the status message but I am thinking to add support for other Twitter APIs. There are bugs in application (not saving credentials in SharedObject, bad graphics, bad user-interaction (UI, soft-key-mapping). I would post the code later after fixing/cleaning.
Meanwhile, if you are interested you can try running this on your FlashLite 2.x enabled device.
BTW! I have Nokia N90 so I made it for it’s screen-size..
