I was wondering if the location services on my iPhone 3G uses cellular data?
I don't want to turn it on until I find out
Yes, it uses a very small amount of data. What location services will do to try to determine where you are is first it will do a cell tower traingulation for a rough estimate of where you are. next it will do a little IP traffic trying to check your address against known wifi hotspot locations, and lastly it will turn on the GPSr in the phone to get the most accurate location. It uses the the methods in that order in an attempt to get a "good enough" location without spending the larger amount of battery it needs to fire-up the GPSr chip and get the ost precise location. The amount of data used by location services is nothing compared to the amount of data the services use for other purposes.
Is there any way to use location services without using data? What would happen if I had cellular data off and used location services? Would it skip that step?
I always have location services turned on, but I usually use less than 1GB per month. But again, having location service turned on or off doesn't have that much affect by itself. It's the apps that you use that do something with the location data that use up data, not the fact that location data is on or off.
Some people who always have location data turned on may never go near 2GB. Conversely, some people who have the location service turned off can go over 2GB. It all depends on what apps you use.
I have location services activated on several apps. I also have the 2GB plan but I only use 200 - 300 MB a month. It may not be the same for you because I'm not a heavy data hog; I don't stream hulu, pandora, etc.
But it wont use a lot like i would be ok with the 2 GB i picked?
