move any app to the sdcard that doesnt have issues wit being there. i usually keep system apps on cadr but any other app except for widget you can move. that will def help. alspo clear your dalvik cache every now and again. trust me it works wonders.some people even report problems such as one instance someones gps wasn't working then they clear dalvik cache and all issues go away. GLD can probably have some good insight on this as she uses sh2 which is huge and has 126+ apps as p.e is still screamign fast on her phone.
