It can be jailbroken but not unlocked. You will need to use a sim from the carrier the phone is locked to. Doesn't matter if it's pay as you go or contract...

Your welcome,

I think only apple can tell you what network it's locked to unless you try different sims until you get one that works. If it's a USA iPhone it will be AT&T...

Although it can be jailbroken, it will be a "teathered" jailbreak at the moment. All that that means is that every time you power off your phone when you turn it back on it will be in recovery mode and you will just have to plug it in and run your favorite jailbreak software.

The dev team is working on an "unteathered" jailbreak that will allow you to power on/off your 4.2.1 iphone 4 and keep your jailbreak, its due to be out on or shortly after Xmas.

You can discuss jailbreaking freely here. Best getting the phone working and activated before jailbreak so you can make a backup first.

The only jailbreak you can do is redsnow. As already explained it will be tethered for now...
