1. What does installer do..? When I jailbroke my iPod Touch before app store I used it to instal apps n' stuff. Then I unjailbroke it because of app store then I just jailbroke it now and there's cydia and installer. I use cydia for games and stuff n' stuff but what does installer do now? 2. I really don't get what these are? I downloaded a theme (complete) off cydia and some WinterBoard App came up on my home screen thingy.. I use this to change themes but wtf is spring board and summer board? I hear spring is some thing that changes the desktop of your ipod touch or something? Cause I used the theme(complete) thing from Cydia and I used it to change the background with the Winterboard thing.. So what are these 'boards'? 3. How do you put a .app onto your ipod? The app I want is just some picture of a camera that doesn't do anything just make it look like an iphone.. But I already have the app but it's named [name].app how do I put it on my iPod Touch?? (Btw It's Jailbroken.) 4. How do you delete apps you downloaded on Cydia? 5. You can't upgrade a jailbroken 2.2 to a 2.2.1 right?
