George Hotz aka GeoHot, the iPhone hacker who was responsible for the first hardware unlock on the first gen iPhone, just posted an interesting image on his blog.
iClarified was the first site to break the news and give us some insight about what all these crazy codes mean:
Details of the exploit are still being gathered; however, it looks like GeoHot was able to insert a custom command to iBoot meaning sigchecks have been bypassed (thanks mav). This should be a start for the iPhone 3GS (N88AP) jailbreak which has been dubbed purplera1n.
That is some very good news for iPhone 3G S owners (me included) who are eagerly waiting for a jailbreak. I guess time will tell. Keep your fingers crossed!
