Yeah didn't even think of that. I forgot quadband didn't include 2100.

Still it's not too bad if you can pickup a prepaid sim. Sadly everything
I see - while you can do prepaid - it's a monthly cost and not a small

Anything where you want to communicate over GSM. So for example one
usage might be a system to unlock your front door with a text

There would actually be some really interesting things if you can do MMS
- like a remote camera system for time lapses.
