I've found a few interesting USB\Nokia charger gadgets during my recent shopping spree on Amazon.com:

MusicPower Encore Dual Port USB AC Charger with Rechargeable Extended Battery #0900-72

It's a USB charger with an interesting twist: it has 2 USB ports and onboard battery for portable power. There doesn't seem to be any mention of the battery capacity, so it may be super wimpy. I hope not. $30

Kensington USB Power Tips for Nokia Mobile Phones 24512

Retractable USB cable, USB stub with 2 small USB-Nokia (old and new) converters. $20

Datexx AA USB Power Bank Cell Phone Charger (Pack of 2)

USB charger powered by 4 AA batteries. Comes with phone charging tips also, including Nokia. $27 for two.

I'm still waiting for them to be delivered, if anyone is interested I can do a follow up report when I get them. Just give me a holler.
