iPhone 3G and 3GS have a GPS receiver. The camera doesn't have a flash, so I'm not sure how it is for night photos, though.

is the GPS on Iphone going to cost money to use? as it has to half use the cell masts for location...
|Quoting Klaus (Reply 3):|
Like most other phones, the iPhone uses assisted GPS, which means that it downloads the current satellite tables through the internet in order to save lots of time (the satellite data downlink is very slow by comparison) and on top of that cell towers are indeed used to provide a "rough fix" initially.
The result is that you will get the rough fix within very few seconds with the final fix not far behind if there is at least some satellite reception.
Using the GPS doesn't cost money to use per se, but in order to work as well as it can, it needs data access.
If you've got WiFi access, data will of course be pulled through that.
