"Smart phones have come a long way in design. Nowadays, they come in all shapes and sizes--from the sleek to the small--and not just the bricklike variety. Yet there's one form factor that the phone manufacturers have yet to conquer--flip phones. The Cingular 3125 was a good effort, but its Trekkie look isn't for everyone. Enter the Verizon Wireless PN-820. It's certainly not sexy--some might call it dull even--but the design is practical and more important, functional. Plus, the Windows Mobile 5 smart phone packs in Bluetooth, EV-DO support, and good performance. Of course, we have our share of complaints." 
The Verizon Wireless PN-820 clam shell smart phone was launched quietly. We didn't see any fuzzy spy shots, there were no pre-production reviews and no launch buzz. The CNET review is probably the first one, and it took over a month for the first review to hit the Web.
Regardless, the clam shell design is pretty popular. There aren't many smart phones in the Verizon Wireless stores right now that can match PN-820's skills. I agree that it is not as cool looking as the Cingular 3125, but it looks like a very practical gadget. What I like the most is that it has a miniSD, yes miniSD, slot that is externally accessible. If you are on the lookout for a flip smart phone on the Verizon's network then check out this Windows Mobile 5 device. In case you own one, we would like to hear about it.
