In case you wonder how he achieved the hack in the first place, here's what he used:
- Guitar pick
- Soldering iron
- Fine pitch wire
- Unlock switch
If you're thinking about following in his footsteps, be forewarned: Using the method could 'brick' your iPhone. It also invalidates the warranty. It is, however, completely legal, per the Digital Millenium Copyright Act. Selling the hacked phone is a whole other matter entirely that is still playing itself out in the legal realm.
