Sprint’s new faster Spark network may be out of reach to most Americans, but it is starting to get more support from handset makers. Sprint said it would start selling a Spark-enabled version of the Samsung Galaxy S 4 in the next few weeks, which can tap into the faster network speeds of its new tri-band LTE network. Unless you live in New York, Los Angeles, Chicago, Tampa or Miami you won’t see those improved speeds, and Sprint is taking it’s time rolling the upgrade out to the rest of the country. The S 4 joins the HTC One Max, Galaxy Mega and S 4 mini on the Spark roster. They’ll be joined by the LG G2 next year.
