bradholland Posted March 2, 2009 Share Posted March 2, 2009 Hi Just got an iPhone for my birthday, wanna unlock it. stupidly, when i first plugged it in, i let it upgrade its firmware from apple software update, it updated to 2.1.1 i think. however i now cant use the yellowsn0w as the update also updated my baseband firmware to 02.30.03. is anyone aware of a way to "downgrade" said firmware of the baseband so that i can get yellowsn0w to work.
