How hard would it be to port over an appstore app to work on 1.1.4 Firmware? I have a first Gen iPhone Jailbroken and Unlocked So my understanding is that I can not update without Bricking my iPhone, But there is an App named GrandDialer that works with Googles Grand Central Service which I use on a daily basis. I would Really Love to have this app on my iPhone. Is this possible...
