I'm using a HTC Hero, and i have downloaded some .apk files from several websites for the applications i want. I put them into my Hero's SD card, and installed the applications using AppInstaller.

After installation, i deleted the .apk files. Will it affect the applications in any way? Because my iMusicTao is not working properly right now. I can browse for songs, but i select a song and it takes forever to load. Any idea? :shoutout:

Nope, they are just installation files. It doesnt affect the program once installed.
