Maybe the iPhone has really been an over-the-roof success but hey, haven’t we heard some complaints about AT&T’s network not being capable of keeping all iPhone users reachable at all times? Hence we have the cool new iPhone application called ‘Mark the Spot’ that takes the geolocation of the user and reports the problem by specifying its cause. This, may be, will help the carrier perform better.

This helps AT&T learn more about those regions where there is not connectivity and things like that. Pick it up from the App Store.
