Does anyone know what this is???
I have embedded systems experience, but I´ve never worked with ARM processors. Does anyone make sense of this?? Obiously it is a routine writtten in Assembly.
It seems the path on the left is the simpler one... Any thoughts?

if it'something related to an exploit or an unlock or something to get from the iphone 3g, it's incredible that a "common" boy can beat the apple's engineers in a short time amazing geohot!

just know 1 thing that Geo still keep the process up. Cos I was sad when reading his previous entry told he cant keep up.

So I think that's the good news.
