is it possible to upgrade the OS to Android 2.1?
go to cyanogenmod.com their wiki has everything you need to know to root and upgrade to Android 2.2 even.
Officially, no. T-Mobile stopped supporting the phone shortly after the MyTouch 3G dropped. There were tertiary promises to bring the device to Android 2.0 back in the start of 2010, but due to the G1 being under-built at launch, this was dropped in favor of developing new phones that could.
Unofficially, Cyanogen is doing wonders keeping older Android devices up to date when otherwise neglected by manufacturers. To do any modern Android install on the G1, you'll have to do some pretty major firmware mods that can completely brick your phone (ask me how I know!) if you do not follow the directions exactly.
