I had an iPhone whose firmware version was 2.1.1. I had hacked it using the method of replacing the MobileInstallation.framework file. I have installed tons of applications since. Yesterday, I updated my firmware to 3.0.1. And successfully jailbroke it. It works perfectly now. But I find I can no longer install cracked applications like before. I read somewhere about using AppSync to fix this problem. Can someone please clarify me on this?
add hackalu to your repos, then get appsync and i think one other thing from there. there should only be like 4 things from the hackalu repo. also there is a thread on here somewhere about installing apps via installus so just find that app as it says what you need to put on the phone.
