Whatever Robert and AJ suggest is likely spot on. In fact, it IS spot on. So consider their awesome information wisely.
On another note, I was at a Sprint store in Buckhead last night here in Atlanta (had to get a replacement battery because my significant other decided it'd be fun to dunk my GS4 in beer at my birthday party on Friday night) and I had the chance to try out 3 spark enabled phones. All of them were connected to band 41 at the time even though Atlanta hasn't yet officially launched as a Spark market.
The three phones were: the LG G Flex, the Samsung GS4T and the Samsung GS4 mini. All were pulling download speeds in excess of 42 mbps with the G Flex topping the list at over 49 mbps. I was BLOWN away. I got my new battery and fired up my GS4 (on only 1900 mhz) and was still impressed at around 9 mbps. That's more than enough for anything you're gonna do on a cell phone but to give you and idea of what can be...well, 40+ mbps is what can be!
You've got a decision to make. Hopefully the info you've gleaned here as well as from the Sponsor maps will aid you in your decision making progress.
Happy Wednesday!
