after a visit to USCC with no real Froyo date, 2.2 leak got a new home on my Mesmerize...was a lot faster initaily but as expected it is slowing down to a more reallistic pace as i have reloaded the apps, files and accounts...biggest improvement to me is the new stock brouser, big speed bump here, and a lot of little thing that seem to make the overall experience more enjoyable.
Battery life is yet to be seen and we will wait a while to finish the setup, let the phone settle in and get back to a bit more normal useage.
Cheers
