Help my V3i is going flat and I'm at a friends house who have a PC and a mini-usb cable. Where do I get the V3i drivers from for Windows XP?

Now that's a question I found myself asking a few weeks ago. The usual search on google provided no useful results.

Motorola's USB Drivers or try Alternate V3i Driver for Windows XP
