Downloaded cyanogen 5.0.7 today, let's just say I am really happy. Not just because it is 2.1, but wow because it is faster, more features, access to eclair apps, slider unlock screen with a sound on/off slider (for the movies ), nexus one splash screens and wallpapers and ringtones. More settings and options. For all those who have been saying I am going to root and haven't you are missing out on this one. I really like cyanogen because they have a wiki with step by step directions, a forum to ask questions, a twitter feed, a Facebook page, awesome support. And they have announced they will continue to work on the G1 as far as 2.2. The sdk has been released and cyanogen is already looking at it for the G1/mt3g. Did I mention it is fast and stable. Did I mention automatic apps 2 SD.
