Many people asked me to create twitter account so they could follow up-to-the-minute progress. So I created a facebook page instead because my twitter account is for personal use :P
The FB page offers more features like photo albums and discussion in addition to twitter-like short updates. Feel free to subscribe to it. This blog will contain only more major updates.

As for progress: firmware upload is still being worked upon, should be done today.
