Can consistently peak over 20Mbps on Sprint LTE even indoors, but it depends on location. Typical is around 6-8Mbps, which is fine for a smartphone. Apps don't need more than a few Mbps anyway. Latency matters more after a few Mbps. Would rather have 3Mbps unlimited than 100Mbps limited (for a phone). Am using 6-10GB per month on LTE and don't have to worry about watching a meter.
Sprint has proven they can do LTE well, now that just have to upgrade every cellsite, which won't finish until next year. 800Mhz LTE starting later this year will help fix coverage issues too.
