I have the bad habit of losing my iPhone through the house. And I'm looking for like an idiot for hours. Is there an application with which to send a SMS to the iPhone from another phone and start an alarm or a default ringtone at full volume, so I can hear it? Because my default ringtone is a slow one...Something similar to "Where is my droid" on HTC? I did find only those applications that track the phone via GPS, which does not help me. Any advice is much appreciated
