You can get them jailbroken for a couple of pounds from Ebay, i got mine done not long ago:)
Nope - you would be charged by whichever company you switched to !
as far as i know, only 1 phone can, a Jailbroken iPhone with the app mxTube
you sell it saying its jailbroken and get ritch and buy a new one
AT&T charges for it, if you're jailbroken there is a Cydia app for it called 'blacklist'.
dtunes is a good one of you are jailbroken... there is none for a nonjailbroken phone
it will not update and if it does it might lock your phone and you will not be able to use it.
Jailbreaking can only be done for iPod Touches and iPhones. No other phone has the ability to be jailbroken. For an iPhone, you need to download a software from the internet to jailbreak it.
You ll get for not jailbroken . Factory unlock will sell for more.
I can't tell you exaclty how this is done however i do know that it requires your iphone to be jailbroken as you need to manually insert it within your filesystem via SSH (something you can only do on a jailbroken phone)
