Hi,
Actually why not go to ebay and buy a new
unlocked (make sure its unlocked) Sony Ericsson T68i triband for <$100 and get a sim in France?
I have a T68i (had it for almost 3 years now) and its a good phone...a little slow in terms of software speed but otherwise a good phone....IMO an easier phone to use than motorola tribands and better interface...Nokias are good too.
On ebay:
For any SE Triband phone:

For any Nokia Tribands:

Again, make sure it is unlocked.
Good luck.
