I have only 1 cell phone but with dual sim card. SO, enjoying 2 numbers (1 official & 1 for family & friends) through 1 cell.
I have (2) cell phones but oddly enough my iPhone is the phone that isn't serviced but my blackberry is....weird (if you're an iPhone lover like my self).
I have two phones but i hardly use my 2nd phone. I generally use my 1st phone more as that one is lucky for me.
