Can you get the Compass application from the iPhone 3Gs to your iPhone 3G?
No, it doesn't have the thing in side the phone to make it work
No?... That's odd!...
does not have the magnetometer or however you spell it.
Edit: beat me to it.
Well Steve Jobs.... that sucks!...
Sorry for being so basic with my explanation i tried to search for the correct terminology, but the 3GS has a build in magnetite compass thing (like in your car). The app would not work with out it.
edit: its called a Magnetometer thanks to everyone above. I had the edit window open as I was googling
The magnetometer, or digital compass is hardware. The compass app uses it to determine your direction, otherwise it doesn't know what to do.
It's like having the phone app on your iPod Touch.
I thought it uses the GPS in the phone to know my north...
Nah Gps just shows position. It really has no idea what way you are facing unless you are moving it can show which way you are moving..
The closest the 3G can come is using a compass app (third party, not apple's) that uses the accelerometer to determine the orientation of the phone. Basically you set the compass app to be calibrated to as close to north as possible, then you get a reasonably (relative to having no compass at all) accurate reading of the direction you are headed. It works in a pinch if you are able to properly calibrate it, but is no replacement for the real thing.
