using 1.6 JB2.
pros:
- glad the unlock screen is working nicely
- nice to have the new android market
- have access to some 1.6+ apps like the new maps, gesture search and google goggles (although the latter is useless IMO)
cons:
- battery life sucks (it was never great on 1.5, but it's worse now)
- camera broken- seems to take pics but they appear in your gallery as a grey "x", so they never get stored. might be just me because i've not read anyone else having this problem
- it is extremely laggy and slow switching Activities and using the marketplace
- lots of force-close/wait prompts, particularly when returning to the homescreen
- missing copy-protected apps in marketplace but that's to be expected given that it's a leaked firmware
- low media volume (can barely hear it on the tube!)
looking forward to trying a new build because the lag is killing me, but will stick with it because it's good to have new market and 1.6 apps.
