Sprint may have been a bit late to the LTE party, but they are making up for lost time. They just issued a press release detailing over 100 new cities that they will be upgrading to 4G LTE service within the coming few months. The list hits a number of major cities coast to coast, and several places in between as well. The list is rather long, so rather than post the full press release in the thread and taking up valuable screen real-estate on the front page, below is a link to the full press release and list.
