Yeah, I've got Donut on it now.

Unfortunately its https library uses some obsolete crypto technique --- TLS 2? --- and as a result it can't connect to anything on the internet, not even to fetch updates from the App Market (not the Play Store!). I can't even log in to Google.

I did have Gingerbread on it at one point but it was very unhappy.

I found a partial Debian port but there's still not really enough RAM for that. I wonder if there's a NetBSD port...

Yeah, I also tried Cyanogenmod Eclair and Froyo on it, but it was an excelent way to waste a lot of time watching things happen in slow motion. So I flashed it back to Donut and few weeks later got another phone, that ran Froyo properly.

I didn't know that the App Market doesn't work anymore - about 18 months back, my brother was still using it (as a backup phone, obviously).
