This RAZR phone is nicely sized and easy to use.  It is not quite as comfortable of a fit on my ear as my old StarTac, but I'm sure I'll get used to it.  Buying an unlocked GSM Quad band phone offers the ability to travel out of the country and connect in to their networks at very reasonable per minute rates.  Also allows you to access stateside or overseas service without long-term contracts (e.g. monthly or prepaid). Although almost of the entire world is using GSM technology, not all US carriers are GSM.  Surely, T-Mobile and Cingular/AT&T are GSM and there may be a few others. I would make this purchase again.
