There is an Application called.. App2Sd you can use it to move your applications to sd from phone memory.. Or maybe search for some application which installs your application directly to SDcard rather than the phone.. I'm using Wolfbreaks rom and it got a tweak in which I can choose whether to install directly to sdcard or phone memory... so there should be some application to install directly to SDcard.. App2Sd is good too .. It will remind you in the notification bar to move the installed application right after you install it to your phone..
