Tringme flash widget works great on N800. Great quality. However, their phone widget it little big to fit on screen but manageable. Hence, I often use their push-n-talk with preconfigured number.

Actually, it worked much better than my expectation. To be honest, i didn't expect it to work from the tablet. But all I did was fire up the browser, login to the website and start talking. I love the fact that I don't have the install some application upfront to use this service.

Cool service indeed!
