I have just recently started delving into my d1 true ability and rooted. I started with CM 6.0 and have really been enjoying it. I followed the rooting instructions on cyanogenmod wiki and used ROM Manager to dl CM 6.0 I saw 6.1 stable out tonight and used RM to dl and apply. I did backup and wipe. Once booted up in 6.1 my wifi setting did not restore and when I manually entered my SSID it would not connect. After waiting about an hour I was also noticing the market was not dl any of my previous apps, I was however synced with my El Goog accounts.
Any Thoughts? I ended up restoring to 6.0 and everything is back working.
