I don't think that they are working to get us covered very quickly. I don't know about Miami, but I can speak about Pompano Beach. I only know of one tower that has lte. I base that from driving around. Parts of Fort Lauderdale and hollywood are up , but only a tower here and there. According to credible reports, Miami, Hollywood, Fort Lauderdale, pompano beach, Deerfield, and some other cities throughout Florida are suppose to be operational "in the coming months", And Their entire network by the end of 2013. Some people say that our area (South Florida) was suppose to be ready by the end of the year. I don't think that will happen. I have been tempted to jump ship, but I think I am going to stick it out with Sprint . I have unlimited everything with absolutely no caps, unless I roam. Sprint announced that they plan on keeping their network truly unlimited even when lte is fully implemented, but if it turns that they bit off more than they can chew and get rid of unlimited data, then I hope they grandfather in their unlimited customers like Verizon and AT&T have. If they don't, I will jump ship then.
