programs that have been ported to 2.0

Jul 21, 2008
I have been on the computer for the past 5 hours learning about cydia, installer (i just got my iPhone on the 11th and didn't mess with jailbreaking today), and basically i learned that since theres a new firmware out none of the old programs work, which explains why when i manually install apps onto my iPhone using cyberduck's sftp, they appear as icon, i tap them, and then they load up and quit about half a second later. so being that there are quite a few iPhone gurus on this website, i was wondering if anyone has any suggestions of applications that have been ported to 2.0 already that i could download? thanks for any and all help
