So I broke my iPhone 4 recently (unusable, battery dies in 1 minute, back is cracked, wont fit in any case, carrier doesn't work) and im temperarly on my iPhone 3G. I jailbreaked it and installed most of the apps that I can use. Is there a way to overclock the iPhone 3G On iOS 4.2.1 using a cydia tweak or iFile? Don't suggest iOverclock, its fake.
