Don't expect to see a call for beta testers until a week before launch. The update will need to be pretty solid before they lab test it on guinea pigs. Besides, do you really want to risk messing up such an indispensible device?

Forget about the SDK. Not going to happen unless there's a significant policy shift at enTourage. For reasons known only to them, they do not actually want to release the SDK.

Wikipedia's info on Flash Lite 4.1 only indicates it's the latest, and supports "ActiveScript". Because of the limitation of the current eDGe hardware, full Flash 10 isn't possible. Flash Lite 4.1 is a poor man's substitute for inadequate hardware. We can expect it will have better video support, but it's not clear how well it'll support Flash websites. If anyone has a link to a detailed description of Flash Lite 4.1's capabilities vis-a-vis Flash 10, please do post the URL!
