In a recent press release announcing its HSPA+ expansions, T-Mobile referred to their upgrades as "4G speeds" several times, which may lead many to believe that what T-Mobile is rolling out is actual 4G rather than upgraded 3G.  AT&T has spoken out against T-Mobile's announcement, responding by saying that T-Mobile needs to "be careful that they're not misleading customers by labeling HSPA+ as a 4G technology."  AT&T, who is planning to upgrade their own network to similar HSPA+ speeds before making the jump to LTE/4G, said that they are not labeling the upgrade as 4G, so T-Mobile shouldn't either.  While T-Mobile isn't technically saying that their network expansion is 4G, their wording could lead many to believe that it is since most people probably don't really know what 4G actually is.  What are your thoughts on this situation?  Share them with us!
