   Not to your face. hehe. Seriously, I basically have an open mind 
policy. I'll listen to any idea, steal the good ones, and pretend they
  are mine. just kidding.

  You would be surprised how many people asked for A GTA02 -GSM

  basically if you look at the costs of BT,WIFI,GPS, you are not talking
  Big bucks. The big bucks are GSM, LCD, touch, processor.

  BT, GPS,WIFI are peanuts.

  I could prolly do tthe Gta02-GSM-Glamo for 199. sold direct of course.

  And the markets you identified are exactly the kind of guys who came
  at me. If you need telephony get a dongle..
