I found this on another forum and found it very handy.
WHAT TO DO "AFTER" YOU JAILBREAK AND UNLOCK! great info ALL N00BS READ!
first and for most, im assuming you already have cydia installed, but if you don't open the blackrain program and tap on cydia, ignore rock this will in time **** up your phone.
once cydia installs open blackrain again and tap uninstall black rain should be a lil red dot next to it click that click delete.
open cydia, it will ask you if you want to upgrade after it loads, click complete upgrade, your phone will restart or might just close out of cydia.
open cydia again, and it will ask you how you want to view things... i chose to view everything so i think you tap on developer.
now for the good stuff...
in cydia click manager at the bottom
click edit at the top
a url box will pop up add each of the following one at a time.
SiNfuL iPhone Repo
cydia.install0us.com <----the 0 is the number zero not letter.
once you have done this the rest of the apps i list just search their names using the search feature at the bottom of cydia. once you search them tap of them and then it will take a few seconds to load the info, then you can scroll down and click on more info or screenshots if you want to see more about it... my descriptions will tell you more than theirs will, but the screenshots will probably help you make a decision on them.
