    Ok, not sure how many people really care about this or don't already know it, but it took me awhile to find out how to lock my sim card. When I went to turn on the SIM PIN it asked for the current one. I figured out it is just 1111. I searched on this forum and didn't see anything about this. I found it on an AT&T forum. So if it is repeated information I'm sorry.

    Dude, thanks for this post. I needed to know this and your post gave me the answer. I never thought about checking the AT&T site. Thanks, again.

    I concur and validate the above. 1111 is the default sim pin on the iPhone 3G with AT&T as the carrier, in Texas. Thx for the info.
