How to fix some mysterious problems.

I have an iPhone 3g (ATT Network) running 4.2.1. I don't need to unlock the phone. What exactly do I need to jailbreak my device (untethered)?

I know GP won't work with the 3G model iPhone.

I have tried Redsn0w 0.9.6rc8 but I keep getting "Unexpected Error!" after putting my phone into DFU mode. What am I doing wrong?

Use sn0wbreeze (Windows) or pwnagetool (Mac).

Trying Pwnagetool now. So I need to use Expert Mode or Simple Mode?

Also, will I need Tiny Umbrella to trick iTunes into thinking its a valid IPSW or is a custom firmware technically a valid IPSW and I can just skip the TinyUmbrella step?

I don't know about the options as I'm on Windows, but probably simple. You shouldn't need TU if you get it into recovery mode.

Don't know if you've done this yet, but you'd be better off starting off Pwnage in simple mode just until it auto locates the firmware on your hard drive (just easier), then press the 'expert' button and select your firmware and click 'next'. The thing you want to change is under the heading 'General' so double click on that and deselect 'activate the iphone', I'm pretty sure that in simple mode it auto hacktivates and you don't need that and it may cause you issues with push notifications/battery life, you may also want to select battery% but the multitasking & homescreen wallpaper will really make it lag so don't select those, also change the boot logo options by deselecting the custom boot logos, unless you want them of course. Then continue the process.
