How difficult and risky is it to unlock an iPhone 3G? I am thinking about unlocking one myself but I'm not sure how difficult or risk it'd be. Is it similar to jailbreaking it?

It depends, what are you running under the hood?

On a 3G iphone on 3.1.2 there are a few ways to unlock..
1. ultrasn0w
2. blacksn0w RC2 final
3. custom firmware

all three are pretty easy pending on your past experience
on jailbreaking and having the understanding on unlock requirements.
3.1.2 has a modem firmware of 5.11.07 which is unlockable but if you by chance have upgraded to 3.1.3 [then downgraded] at anytime then your modem firmware has changed to 5.12.xx meaning you cannot unlock at all until next unlock release.

But this is just all blah..blah..blah.. until you have answered xxxxpradaxxxx question
"whats under the hood?"

Actually blackra1n does not unlock, it jailbreaks the unlocking tool you are thinking of is "as stated above" blacksn0w.

But until we know what firmware he is on there isnt much we can say.

I do not have not and never will recommend anyone to run Blackra1n when there are better jailbreaks out there to use. I had a sticky guide here for a long time but was replaced by my 3.1.3 guide. You can still find everything you need to jailbreak and unlock here. http://forums.crackberry.com/f99/gui...rmware-441303/
Good Luck!
