I got it as well and as far as I can tell it works. I'll try all my USB / mini cables to see if there's one that doesn't. Hopefully they all work

Thanks for the link. Have you tried it?
I ended up buying that one, yes, and it works.

When its in sync mode, it will both sync and charge, when its in charge mode it doesn't do anything. I've tried every order and combination of plugging and unplugging and its still useless.

Second edit:

I don't completely trust it to always work with all chargers, but so far it has seemed to be working the few times I've used it.

I bought this cable for $8 at Brando's and it charges the N900.
Thanks for this thread and all the ideas.

Does anybody own a New Trent IMP880? Since the ZaggSparq is still sold out, I'm considering buying it. E-mailing New Trent they said it has a USB port but they can't guarantee it works with the N900 since they don't test Nokia devices (only iPhones and Blackberries).

Hoping to get it before Otakon since I'll probably spend alot of time watching videos or surfing on 3G while my sister runs about..

Brando also has a Mini USB to Micro USB adapter with on/off switch, which costs $6. It works the same way as their switchable Micro USB cable, letting you choose between dumb charger mode and PC connection mode. It may be useful to those who have lots of Mini USB cables and chargers.

Update to this post. It works but you can't use the USB cable that came with the N900. You have to use the charging tip they provide (or a charging USB cable with the data pins shorted).

fwiw, a micro usb cable plus wall adapter from a palm treo pro works great

Actually, I think it charges the battery faster than the included ac adapter if that is possible

I've got one of these, along with a USB to mini-USB cable.

Works great for anything with a usb port (except Sky+ boxes).
