Please read the threads about the Nokia chargers. A lot of people reported back saying that they don't charge correctly for the Nexus 4's or they need to cycle a charge before it begins to cycle. Whatever the reason, I would recommend to stay away from the Nokia ones and keep with the LG, Energizer, Maxell, Zens and Panasonic that all reported back working for our phones and with tpu cases on.Someone mentioned in the Qi thread in the ATT Galaxy S3 section that he had found a charger for ~$47 at his Wal-Mart. I got the impression it was the LG one, but not sure since that price looks higher than I've seen mentioned for it. However I can't find it on their website.
So... the only source in the US that might be in stock is ATT and Verizon for the Nokia charger. The V also has the Fatboy charge pillow on their site. When I've checked the ATT site, they only showed black--but their store might have more I guess.
