Overclock the processor of the iPhone 4 to 1Ghz

Iphone 4 (4G or iPod touch) is already the fastest and most powerful of iphones. However, this phone has been crippled by Apple: it is possible to boost the processor at 1GHz in a very simple, without risk of damaging your device. In return, the phone consumes slightly more battery (which makes sense).
In addition, this software is also compatible with older models!

 

Info: The experiment is feasible under ios 4.1, or 4.2.1, knowing that the latest version (4.2.1) saves the battery, I suggest you get your iPhone on this version if you have not already done so.
