not perfect on my xperia x10...
Thanks for the app... however it doesn't work 100% right on my xperia x10 2.1 rooted... I did everything like you said (partitions, install link2sd...)
After sucessfull instalation i tried ,link some apps to the sdcard... however some apps doesn't work... and force close. For instance:
- Angry birds: the only app that did well;
- AppRemover: Force Close;
- Opera Mobile: Closed;
- Tango VideoCall: Force Call;
- Dropbox: Force Close;
- Xda: Force Close...
And some other apps i could enter in the app but if it needs internet connection, the app couldn't get in the network...
This app would solve my problems with storage, because unfortunally SonyEricsson wouldn't bring Froyo to Xperia X10...
