what you need is not unavailable in the usa.. not at all..

ebay is a convenient way to get one - but there are other websites selling them too

you need a world phone or unlocked gsm phone

it has to be GSM, it also has to be quad band.. if you search for unlocked gsm cell phones on ebay youll find a million from simple to smartphones..

i think a excellent choice is a unlocked motorola razr gsm phone.. i bought a very nice one on ebay recently for UNDER $30 delivered.. and it is of a MUCH higher quality then the entry level phones at digicel.. just my opionion
