Okay, so I'm getting really frustrated with this whole deal. My phone crashed so I was forced to update my jailbroken iphone to the new 3.1.3 firmware. Everything I've read on all the forums and everything say I should be able to jailbreak it again. I have an IPhone 3Gs with the 3.1.3 firmware an MB model number and a 359.3 bootrom. From everything I have read I have all the right things to jailbreak but nothing seems to work. I've tried blackra1n redsn0w and am currently trying sn0wbreeze and nothing works. Am I missing something?
