Hi, I have been trying to resolve my iphone issue for the last several hours!!! With Blackra1n I was able to successfully unlock my iphone. I have been using my iphone now for several days until I noticed I couldnt use youtube. After searching the net I found that if I reset the network settings it would all be sorted... Thats when it all went wrong. When I did this the iphone did a hard reset and since then I keep getting the tethered itunes logo. I tried to use blackra1n a number of times with no luck. Until I found an article on using redsn0w as a substitute. I have just tried to use redsn0w and although I seem to successfully been able to install it, it cant boot!!! Just get the itunes - usb logo!!!! Can someone please help me before I go made : (((( ??? Thanks for your time, Paul.
