use meebo.com in safari for a instant messenger
if you near a wifi connection, you can pretty much listen to any music for free at seeqpod.com
and for free sms, goto
Free SMS
i havent been able to get this to work, the msg's dont get received
games goto podcade.com
btw, this is all threw safari browser,
the apps that you can get by jailbreaking are actually installed.
word of advice, if you going to jailbreak use that touchfree program.
then once its on your pod, go to installer, dont install anything..
you want to update the program first, it woulds through the wifi.
you must update the installer to version 3. im not sure exactly which thing it is as ive forgotten. but just update everything before you go ahead with installation on the device itself, otherwise it messes up.
