I should calify. The USB cable actually came with the aftermarket car charger sold by Cricket, but it turned out to be just a power cable.
I went ahead and bought a real USB-to-mini data cable at my local geek shop and it works like a champ.
As for Muve, it was a defective factory SD card. They replaced it and now it works perfect.
It seems there is a difference between the all black SD card that came in the box and the Blue label SD card with the blue one being the good one.
