I got my iphone replaced today and need to jailbreak & unlock it in order to be able to use it in the UK. I am trying to use the iPhone2,1_4.2.1_8C148a IPSW It is an Iphone 3GS, iBoot-359.3, 4.2. Whenever I run redsnow it works fine until the window which should be asking me to hold the power button for 3, then with home for 15, and then home button for 10 seconds. Well I get to that screen but I hold the power button for about 2 seconds and it moves on to the next window. Then it will try to install but just tells me there is an unexpected error and to retry. Whenever I plug in my iphone it says it is a phone in recovery mode and asks me to restore it. What can I do to jailbreak & unlock it???
