Arghh...Please help!

Hey Guys,

So I am having troubles unlocking my iphone, I know there are tons of posts here about this, I HAVE read them but am still unable to understand what Im supposed to do from here. I am trying to get a tellus phone to use a rogers wireless sim card as that is my current provider. I downloaded and installed the new baseband. I installed cydia, which came up white, after some research I was abel to fix that. Now there is no ultrasnow in the cydia app. I did some research and found that you have to add it to the app. What I can't seem to find is how to do this. I have read many on here, giving others 'tude for having other people do their work. I am not trying to take the easy road out here, im just a bit lost, so any directions would be greatly appreciated, i'm the type of guy who is willing to stop and ask before I run outa gas, or in this case, brick or kill my iphone, doing stuff Im not completely confident about! LOL. Pre-Thanks to all!
