Jailbreak often creates wonders like these.
An awesome hacker called Mike has enabled HD Video recording for the iphone 3gs.We all know that the iphone 3gs is certainly capable of handling the HD resolution due to its powerful GPU.But somehow, apple restricted it through software.So, what our hacker friend did was remove it.
The resolution exactly is 1080×800 which is actually termed XGA, is encoded at 30 fps and at a bitrate of 20 mbps, which is humongous. The hacker should be lauded for his efforts of upping the resolution from 640×480.
Redmond pie has given instructions on how to achieve this jailbreak.
