Slightly OT, but I was at the Sprint corporate store in the Promenade (South Charlotte off Providence/485) this morning checking out the Note 2, and while none of the phones were able to connect to LTE, I was getting great WiMax coverage with my SGS2 and had a speed test of over 10mb down/1.5mb up. It has typically been 3mb at the most.
3G was still around 250 kb/s, though.
