[asterisk-users] Cell phone that can be connected to standad phone switch network

[Joseph]

Are there any cell phone (gadgets) that can be connected to standard
switch phone network?  (ability to check email would be a plus).

Digium adapter S101i can be connected to any network and it allow a
standard phone to act as your local extension over the Internet (by
registering to asterisk), it works "almost" perfectly.
So it would be handy to have a cellular phone that can be connected to
standard switched phone network, are there any toys like this?
