Holding out for the Palm Pre to be available on Verizon. Still hoping that Palm can get it right finally.
So I carry two now: K-RAZR for voice on Verizon, and Blackberry (ancient BlueBerry model) on AT&T for email. Hate voice on Blackberry. Technically a third: the one built in to my ThinkPad with Verizon connectivity, and yea, there's a fourth one mounted to the wall that is part of the home alarm system (has to be wireless otherwise the bad guys just cut the outside phone cable and there goes the automatic call to the cops).
Indeed I pay the four wireless bills each month.
I have the first Palm phone ever (it was awful -- made by Kyocera) and the original Star Tac from Mot lying around for smiles, not connected.
Yikes, I forgot -- I have another unlocked quad-band GSM K-RAZR (bought from South Africa) and a very nice quad-band GSM Samsung that work perfectly, we take them on trips abroad (one for me, one for my wife) since our Verizon phones work nowhere but North America. We buy pre-paid/pay-as-you-go SIMs and stick them in -- anywhere in the world -- and we can communicate as we go our separate ways as we do on vacation during the day (she loves the outdoors, I hate it) ... lucky for me we do come back to one hotel room at night.
Pay-as-you-go SIMs usually expire even if there is money left on them after 6 or 12 months of no usage, so if we know we are going back (like to the UK), we stick them in, turn on the phones, link to the U.S. roaming parter (often t-mobile) and send a text message to ourselves ... this is cheap, and keeps the SIM alive for another 6 or 12 months. Great trick taught me by a world-traveler.
What's that then, 6 active? Acutally there is one more, a dedicated Virgin Mobile (not quad or even tri-band) that I got for frequent UK trips before I learned the ways of SIMs and quad-band. I text with it every so often to keep it hot, as explained above, and lend it to friends going to the UK on vacation.
