I have an iPhone 3G (MB) model and have upgraded (now its released) to ios 4.2. So then i wanted to jailbreak it. So as usual i went to redsn0w. I downloaded redsn0w 0.9.6 as that works to jailbreak ios4.2 the website says. So i opened redsn0w 0.9.6b2 and selected ios4.1 software (as you need to select the final version of ios 4.1 at the moment as redsn0w is made for 4.1 not 4.2 but can still jailbreak 4.2 the website says) it all jailbreaks fine and i get my wallpapers multitasking on my iphone 3G again. but then when i touch the screen big fuzzy lines go across the screen. This is only when i touch the screen if i leave it nothing happens but when ever any contact is made with the screen and i touch it a load of lines go accross the screen. I have restored my iphone now and have unjailbreaked it. But I would like to no if there is a soloution to my problem?? Can anyone please help me??
