No. I haven't returned the phone, and I won't be. I'm looking at buying something as posted in the first post, which will provide a home charging solution as well and in the end still be cheaper. Also, repeating myself again, even if I did return it and had no phone for 1 week, it could be argued that is better than not having it for 2 weeks as I was originally looking at.
What car charger are you using now?
OH ok now I'm following what you are saying. Doh amazing what sleeping on it then rereading it does for you! lol, my bad. As far as home charging you should be able to use any microusb cable to your computer, or one of the wallchargers with a usb port, then the cable to the phone. In the car I'm actually using the same charger I used for my BB Storm, so you should be able to look at any charger that works for a Storm/Storm 2. Just something to think about.
AFAIK all usb outlets use 5 volts.
