Plug into iTunes and then turn the iPhone off.
Now hold the on/off button down for three seconds and then without letting go also now press and hold the home button for ten seconds. Let go of the on/off button while still holding down the home button.
iTunes will provide a popup window informing you your iPhone now needs to be restored. Click OK and proceed to restore your 3GS to factory settings.

the phone is locked to at&t, that's why your SIM is not supported (if you're trying to use it on t-mobile or some other GSM carrier)

The phone likely had a software unlock in place and you deleted it when you restored it.

Post the first 5 digits of the serial number.
