Another one of my big questions is....

What's the point of the signal meter in the top left corner of my iPhone 4s?

It consistently displays 3, 4 or 5 bars of reception quality and the "3G" logo, despite the fact that I receive no data.  I downloaded the ROOT metrics app and it confirms that I am either not able to upload or download data, or both.  Yet, the AT&T signal meter on my home screen is showing me that everything is OK.

TO BE CLEAR.... My phone call quality and voice commmunication work FINE.  No problems there.  Regular text messages (not iMessage which is data based) work fine.  I have no real problem with dropped calls.

Data doesn't work.  I am going to call again today and tweet a link to this thread.  I encourage others to tweet a link to this thread as well in order to try to get AT&T Social Media's help on this.  There was an article that I read in the news that touted AT&T's Social Media help as "cutting edge" and widely effective.  They actually seach Facebook and Twitter for people having problems.  (Can someone from AT&T tell me if this is the case?)

AT&T:  Why does the reception meter not display any data that means anything?  Also, please see other question above.

Thank you,

Mike
