The current iPhone is unable to run third-party applications in the background which limits certain types of apps, such as location-based services. However, rumors suggest that the iPhone OS software 4.0 revision will support foreground and background performance while preserving battery life. The same rumor says it  will arrive this summer, while iPad users will have to wait until the fall…But, you don’t have to wait until that long if you download the GPS Tracking app. It’s a peer to peer messaging app running in the foreground and able to locate anyone or everyone in your contact list with a single click and now it can share a photo with its point to point locates. So if you need to know now, now you know where to find everyone you know.
