Those are some of the ways Verizon, AT&T, T-Mobile and Sprint are describing 4G, as they push hard for smartphone users to convert to their new, upgraded networks. But 4G won't fix dropped calls, or a myriad of other service problems that exist, though it could lead to new issues for users moving through areas that lack coverage.
