It really bugs me when I see the commercials on TV for "4G" networks... somehow everybody has the largest 4G network, or the fastest, or the best. The reality is that only Verizon has a huge 4G LTE footprint across the US - the others are catching up quickly, but Verizon has been ahead for a long time. (And yes, I have read that AT&T's LTE is faster in many places).
So instead, the other networks decided their 3G HSPA+ is fast enough to call it 4G, even though it's not. So irritating.
