Hi, I just jailbroke 10 minutes ago. I went to download Mobile Terminal from Cydia to change my admin account and my root passwords. I went to open it, I can't type, and it closes 3 seconds later. I rebooted, and that didn't help. I am using a 2g MC model running 4.2.1, jailbroken by Greenpois0n. PLEASE HELP!
