There was a iOS jailbreak tweak called Treadmill where it exactly done that. Pretty cool to me.

Never owned an iPhone after 3GS because it became prohibitively expensive.
I have so many memories of cydia and there was this itools, some Chinese software that let me do more than iTunes.
Those were the days. I was rocking an html lockdscreen which was pretty cool.
When I got hands on original iPhone back in 2008, I remember my PC having less ram, less storage as that was a handmedown. It was freaking cool to have more compute in hand than what my xp machine did.
I didn't know that, thank you for the information and for your feedback
