It seems that your iPhone 2G is in need of activation. To accomplish this, there are 2 ways:
A. (With AT&T as your service provider)
1. If you do not already have an AT&T sim card, contact AT&T and ask for an AT&T sim card to activate service with them. Choose your plan and insert the sim card in the iPhone.
2. Connect the iPhone to iTunes and you will be prompted to follow a few steps to proceed with the activation process.
3. Sync your iPhone for the first time.
Once completed, you will have your iPhone activated and ready to use on the AT&T network.

B. (Without AT&T as your service provider)
1. You will need to download an application to jailbreak your iPhone. (This will essentially remove certain restrictions on your iPhone 2G that prevent you from utilizing your iPhone on another network, among other things).
2. Connect your iPhone to the computer and run your jailbreak application of choice.
Once completed, your iPhone 2G will be activated and jailbroken. The "emergency call" message will disappear, though you will be prompted with a "no sim card found" message until a sim card from AT&T (or another GSM carrier) is placed in the sim tray.

First option is to put a legit sim card. - this will be a problem if you bought your iPhone from another country.
2nd option is to jailbreak and unlock your phone. - if you've upgraded your iPhone to version 3.1.3, there's a great chance that you won't be able to do this option.
3rd option is to use a turbo sim which you can find on eBay. check out some items i've searched for you. - this option will work only if you have 2.30 or lower iPhone software version.
other than those 3, i don't know anything more.
