Hi, first of all i would like to thank all the great members in this forum, i have learned a lot and finally rooted my phone with gingervillain 1.8. Really like it so far. Now back to question, I know I'm not supposed to use 'move to sd' option since I'm using app2sd (I'm sure it is activated since most of the apps are installed on the app2sd partition), but I notice for some app part of the internal storage are still used, and I am sure it's not data or cache. Take angry birds for example, total size is ~20mb and once installed few mb of my internal storage will be used by the app and once i move the app to SD i regain the space. Some apps can be totally fit into app2sd partition. Can anyone explain to me why is this happening? Also, what problem am i going to encounter by doing moving those stubborn app to SD, other than they can't be used when SD is mounted?
