Some have asked what the advantages of 2.1 are, since some are seeing negatives only. Well here is a thread to list those! 1) Fixed problems with pattern unlocking! Had this in 1.5 it caused lock-ups. Seems to be working fine with 2.1. 2) Contacts entered in phone now sync back to google account. This one was needed, badly! 3) Pinch to show 7 home screens. The advantage? No more swiping 6 times to go from screen 1 to 7. Or vice-versa. 4) Battery life! My battery life doubled just going from 1.5 to 2.1. 5) Ability to dim screen. Further helped with battery life. 6) Turn-by-turn directions. Bye bye GPS unit that requires $60+ map updates. Google maps are updated for free. 7) YouTube app works now. Enumerate your positives!
