Mac OS X Lion is very pretty on Macs, but it looks clumsy and ugly on iPhones.  Hacker Timothy Elliot has created a look alike Lion theme to replace the default iOS theme for iPhones.  To use the theme, you definitely have to do a jailbreak.  With iOS 5 about to be released sooner than we think (I think), I don’t think it’s worth to go for a jailbreak so one can have Lion theme on iPhone.  Nonetheless, if you have a love bug for Lion theme, who am I to stop you, right?  Check out the video right after the break which demonstrates Lion theme on iPhone.
