I can't find anything good on installer.app and the ones that I did download don't even work. Where's the video recorder, guitar and piano and all that good stuff from before? Does it totally suck now or am I just not doing something right?
Are you by chance still on 1.1.4? If so, you're not going to find much new coming out for you, because all jailbreak developers that haven't jumped to the Appstore are releasing things on Cydia for 2.x now. You'll get Cydia once you update to 2.1 and jailbreak it. You'll get installer, too, but it's changed a lot and is barely supported anymore. Cydia is where the majority of developers are distributing their stuff now.
