Today i wa suprised, that i could update my iPod Touch 1G for free to OS 3.0.
To make things clear, i didn’t hack it and it is 100% legal, because the update is free, if you have already payed the 10$ for a previous update. In my case i updated my iPod Touch to OS 2.0 spending the 10$ when it came out. Obviously any (!) sequent updates are / will (?) be free.
Some people commented some posts around the net stating that if you pay the 10$ for one iPod Touch OS update you can update as many of your iPod Touches (1G and 2G) as you like without paying the 10$ again.
