I recently used my iphone to tether. I got it through a download at help.benm.at/help.php I only used it several times for under 2 hours total. Well, now it seems my iphone is dropping calls like crazy! And not while I'm tethering, but all the time. My cousin has said the same thing since she's been tethering. Is it possible AT&T is doing this b/c I'm tethering? Does anyone know if this is related or has anyone experienced this same problem. Also when I downloaded that file, did I "hack" my iphone?
