Ok so i know theres a video here on phandroid that tells you how to get rid of lag...disable javascript and turn the plug-ins to demand only..now you can do that and it will work but if your like me and you want to keep the glory of seeing what flash is for your phone..dwnload an alternative browser..me i got the XScope 6.x browser very fast and snappy there are also firefox, dolphin browser and others to choose from that are infact better than the stock browser also if your having lag on homescreen get an alternative like LauncherPro+(thats what i use) or zeam, golauncher ex, adw ex and many others i promise you the lag will disappear. Hope all works out for you
