Not sure if troll. The answer is no. 5-6 inch resolution means that one pixel will represent 5-6 inches. You wouldn't even be able to see the phone.

Edit: Sorry, understood your comment now. The real problem isn't resolution, it's "getting a good angle". Unless your target and the satellite's orbit are magically aligned at a precise moment, you're going to have an extremely hard time getting a satellite into position in a reasonable time (the best commercial satellites can do is around 6 hours).
