If you do get a razr/gsm phone, the best thing to do is get it unlocked! If you do a lot of travelling outside the US, you can get yourself a prepaid SIM card and not pay roaming charges that your US based carriers will charge. That's why, I'm with Cingular. Their service is fine. I've had my share of drop calls, but since the acquisition of ATT, reception in parts that were spotty have gotten better. Another thing to point out, there are more countries that use GSM and that's the big advantage that GSM has over CDMA.
