Which faster and more reliable? Back up your claims because I'll be making a decision on whether to stay on Sprint or go to T-Mobile on them. T-Mobile has HSPA+ in my hometown of San Jose, CA. While Sprint doesn't officially have 4G in San Jose, I've been picking up 4G signal in numbers places in the city. I can get 4G signal throughout mostly all of downtown, and along most freeways north of the downtown area all the way up to San Francisco. I'm not relying on these speeds as being average, since 4G isn't official here, but I'm getting 4-8 Mbps down and 900Kbps-3 Mbps up on average using my EPIC 4G. How does T-Mobile's HSPA+ network compare?
