you can only get 1.5 officially at the moment. 1.6 and 2.1 are out there as developer ROM's, but it sounds like they work pretty well, with a few minor glitches. I haven't really messed with them yet, but if it's snowing as bad as it sounds like it's going to tomorrow, then I won't bother driving to school and I'll have an extra 6 hours to kill...which means I'll probably tweak my phone some more lol
