alternative to GPS in location-based-services for iphone

Is there anyway i can decide that only with cell tower or wifi i can get location of the phone in iphone sdk. I don't want to use GP开发者_Python百科S at all. Thanks in advance.

You could set the desiredAccuracy to something lower. The iphone will then use the most energy efficient method to calculate location, which normally won't be GPS.

However you cannot explictly tell it not to use GPS.
