    Hi guys,

    I have a black iPhone 4 on AT&T and I want to jailbreak it. Its on the 4.2.1 OS and has a baseband of 03.10.01.

    I want the process to be as quick and as painless as possible. Is there a tutorial I can follow somewhere which can guide me through how to do this? The only time I have ever jailbroken an iPhone was a 3G, and I just used Spirit which did it in like 10 seconds, haha.

    Thanks, I appreciate your help!

    when jailbreaking it will automatically downgrade the software correct?

    What ever jailbreak tool you use, it jailbreaks the current iOS that your device is on.

    Jailbreaking doesn't downgrade/upgrade software.
