I am sure many users are experiencing lag time between screens. Very Annoying, Right? I have tried downloading a Task Killer but that only helped a bit. Since I am new to this site, I am not sure if this has been suggested. I just found possibly an unknown "treasure" and VERY helpful solution. Its "Spare Parts" in the Android Market (USE ONLY WITH 1.5 or 1.6). I downloaded it this week. In settings, I checked-off "Fast" in the TWO "Animation" settings and now its SUPER-Fast! Its like a "Touch Phone on Caffeine!"
