can anyone tell me how accurate the iOS5 region monitoring function can be. i.e. can it use my GPS location to monitor when I enter a region.

Also what is the max number of regions I could configure at any given time.

Thanks for any help

So so accurate for ios 5: should be from 1 to 150 m, ios 6: 1 to 400m

Max number of regions 20 per application.

The notifications are NOT instant though, and there are other things like cushion region and such.

According to apple:

In iOS 6, regions with a radius between 1 and 400 meters work better on iPhone 4S or later devices. (In iOS 5, regions with a radius between 1 and 150 meters work better on iPhone 4S and later devices.) On these devices, an app can expect to receive the appropriate region entered or region exited notification within 3 to 5 minutes on average, if not sooner.
