Im confuse Need my 3G with JB and unlocked what I need to do?

[cdesigns]

Guys I have been reading and reading but, some people say one thing some people say use this (yellowsnow, ultrasnow, redsnow, quickpwn) etc etc etc

I sold my 3G and I need to Jailbreak 3.0 and unlocked so it can be use on other carriers.

What should I do, what do I need to download?

I have a PC not a MAC

Any help will be apreciated

You can use redsn0w to jailbreak your iphone 3g now, but if you want to unlock then you will have to wait for ultrasn0w

ultrasn0w could get a release tonight, could be tomorrow, or it could be anytime

Hello,
I have a similar question (sorry if I hijack the tread). I'd like to help a friend who has a JB iPhone 3G and he's using his carrier SIM (he doesn't need to unlock). His OS version is old 2.1 (5F136). Can you confirm that he steps to update to OS 3.0 would be the following:

1- backup
2- restore via iTunes (update to official not JB 3.0)
3- JB using PwnageTool 3.0 (I have a mac)
4- no meed to unlock since he's using his carrier sim.

Thanks,
Tex
