Ryan from engadget discusses iPhoneSimFree on TWiT
It's the first topic they discuss, a couple minutes into the podcast.
Ryan says that the software unlock he was presented had to be installed on the iPhone, so it takes some prior hacking (not that anybody here should have a problem there) but he went on to say that he didn't know if that necessarily would be the final solution they came out with.
The show was recorded on friday, so they talk about iphoneunlocking like they're actually were gonna release their unlock on saturday. Little did they know..
Anyone still doubting iphonesimfree is a nut. There, it's been said.
