I have iPhone 2G ios 3.1.3. This is a jailbroken iPhone. The bottom bar of my phone is completely freezed (dead). This is a hardware issue. But i want to know is there any fix or application through which i can work with this phone having freezed bottom bar. For example if there is any app which reduce the display size on touchscreen so that i do not need to touch that freezed(dead) part of touchscreen.
