The dev team is still releasing updates for their 3g unlock. It is important that you update regularly if YellowSn0w is not working great for you. They also released some hints on their web site:
1) If you are on tmobile USA you should disable 3g in settings or sbsettings.
2) YellowSn0w does not work with a SIM PIN. You must disable your SIM card pin lock.
As I said, if YellowSn0w is not working great for you, keep checking their web site for updates.
If yellowsn0w isn’t working for you take out your sim card and look at the numbers printed on it. There are 4 horizontal rows of numbers and 1 vertical. Look at the first 2 digits of the vertical row of numbers if it starts with 36 or higher you will not be able to use yellowsn0w (yet). Dev-Team is aware of the problem and is working on fixing it.
There is also a user-generated success and failure report here.

BigBoss, are you referring to the AT&T SIM card? If you are, then yes, I have numbers on it, but no they are not as you describe. I have:
Top
- The AT&T 3G logo
- A 20-digit number under it (all numbers)
- The AT&T logo under the 20-digit number
Bottom (all on the left side)
- The AT&T 3G logo
- A 5-number, 1 letter line (NNNNNL) under the logo
- A 4-digit number underneath the number/letter line
Please let me know what to look for, if the AT&T SIM is what you are referring to. Thanks a bunch!
And you RULE!!

Why the heck would you unlock the 3G just to stick an AT&T SIM back in it?
Hello?

Iphone crash and just goes to safe mode after installing apps from cydia. anyone here with the same problem?

only happens after installing winterboard.

You know…. some people travel overseas. Would you (or anyone) pay AT&T for the International roaming? I’m not rich, so I’ve always bought local prepaid SIM card and SMS all my contacts to inform of my local number. Unlocking my 3G will eliminate the need of a second GSM phone.

Couldn’t have said it better myself.
