There's nothing like keying 300+ contacts to your cellphone, only to have something catastrophic happen and lose them all. Sure, providers offer certain forms of backup, but a new service from Plaxo will make all your worries over losing that oh-so-precious contact list disappear. The firm is hooking up with Verizon Wireless (with Alltel and US Cellular to follow suit) to offer automatic list updates from "commonly used e-mail systems" (such as Outlook, Yahoo Mail, OS X Mail, Mozilla Thunderbird, etc.) wirelessly via its Plaxo Mobile Plus system. Customers will still have to choose which names receive the honor of being placed in their always-available contact roster, but the service "eliminates the need for manual reentry or copying directly from a computer." While specifics weren't given, this convenience is slated to work with "30 Verizon Wireless handsets" initially, and run customers $4.49 per month, which seems like a lot to ask unless you're notorious for destroying phones.
