I am having an issue I have never experienced before. I updated to 3.0.1 and am attempting to Jailbreak using Redsnow 0.8. The problem is I cannot put my phone into DFU mode, every time I attempt to place the phone in DFU mode using the common technique it turns itself off after about 6 seconds of holding the home and power buttons together. Does anyone have an alternate method? Any help would be great!

THanks in advance!
