I have upgraded my phone to 2.0 and I have the 6GB 30$ data plan so now the only thing missing is a GPS program I can run. I have heard that some companies and working on stuff but do you think it will be at all possible for me to have a GPS on my phone? Right now I have everything except 3G and the GPS, the 3G I can live without but the GPS is one of those toys I would love to have.
Thanks for the replies

Sorry, no go. The iPhone 3G has a GPS receiver in it. Your iPhone does not.

If I remember correctly there is/was a pseudo GPS type program that would try to find your position based on available cellphone towers/signal strengths Wifi networks etc.

I believe it required a jailbroken 1st generation iPhone and a specific firmware.

Also - the margin for error was much larger than with a real GPS - I saw it working on a friends 1st gen iPhone and it placed us within a few blocks (4 or 5) I think it was "Navizon" or something like that.

It wasn't true GPS, but it was an interesting toy and might be useful in some situations.

Well I guess I can live with that so not all is lost, I'm still happy I have a data plan now.

All GPS/location programs use the iPhone APIs. On your first gen phone since it doesn't have GPS it just falls back to cell phone tower and wifi triangulation. The same thing happens on the 3G phones if it can't see the satellites. It's accurate enough to get a general idea of where you are. The only annoying thing is when you press it on Google Maps it keeps zooming to the default zoom level so you have to keep zooming in/out.
