    Hey guys

    I have an iphone 3g 8gb on 4.2.1. I have tried to jailbreak it via redsn0w but for some reason the iphone cant enter dfu mode. I press the home button and the sleep button at the same time but the iphone doesnt restart for some reason. both buttons work perfectly fine when the phone is on.
    what could be the problem?

    I had a problem as well the last time I tried to jailbreak. Wouldn't enter dfu mode.

    Turns out the Apple Recovery (iBoot) USB Driver was missing.

    Repaired the Apple Mobile Device Support installer package, and now all is good
