jailbreaking

[user130523]

is jailbreaking an iphone illegal?

and will it affect downloading the latest updates etc (currently on latest version - iphone 3gs)

[Jam]

Its not illegal and you just restore the phone in iTunes and then upgrade (and wait for a jailbreak of that version).

[Stephen]

if you update your iphone after jailbreaking then you'll have to jailbreak again

but greenp0ison released the untethered jailbreak for 4.2.1 like last week or something
