have you read the rooting thread? if you have atleast the H1 firmware, rooted then overclocked with the memoryapp you phone will be as fast as desire, n1 on 2.1.so if we update the firmware, no longer 3 sec for each button/task we press/executed?
With no official 2.2 update the only upgrade we can hope to get is the release of the beam source code by Samsung then we can get some custom roms going.
