So finally feel like I'm ready to dip my toes in the jailbreaking waters here. Have been reading up and noticed on the flowchart in the sticky at the top that they advise those with a 3GS + old bootrom + 3.0 f/w to go the redsn0w route to J/B and then upgrade to 4.0 custom firmware with Pwnage Tool. Just wondering why this route is suggested for my model/firmware as opposed to the newer (and seemingly easier) jailbreakme method??? I feel like I'm missing something. Thanks!
