Looking for a travel phone

I want to get a unlocked GSM phone to use when traveling abroad. I like the Motorola FONE F3, but it doesn't use a 'standard' micro USB charger. Since I already have quite an extensive collection of chargers I would really like to not have to make an addition for the phone.

Other than that cost is the next criteria, under $100.

Criteria after that are just wishes. Quad-Band GSM would help. It would be nice if it had a usable gmail app. A small blackberry-esque keyboard would be cool. Most off-the-wall-wish: that it could function as a wifi hotspot.

I have a Samsung Reclaim, which would be perfect but for the fact it is not GSM.
