Around the World

I do a lot of international travel in my work (primarily Ukraine, Croatia, Republic of Georgia, and China) Recently in ROG a friend there loaned me an Ericsson phone with a local SIM and I simply purchased phone cards for calling back to the states. What a deal! I am a Cingular subscriber and am looking for a suggestion on a phone I can purchase to take with me on my travels. I like the idea of purchasing a SIM locally so it doesn't matter to me about using Cingular service. Any suggestions?: 🙂
