How to do stuff

[schamber]

Hi, I am fairly new to the HTC Touch Pro 2, I love this phone but it can be better, how do I exactly customize all the backgrounds and put .cab folders onto my phone, do i need to like jailbreak (like the itouch) or just throw in the files. Also when I downloaded some games from freeware game site there was no .cab file when i extracted them. It would be awesome if I can get some help, this is a wonderful forum.
