I'm in Boston, we've got LTE. My iPad said 4G initially, but after a second or two, it says LTE in the status bar. The AT&T iPad does indeed differentiate between HSPA+ and LTE.
Tricks like what?
Calling HSPA+ "4G."
In the end, I think it's counterproductive. People in Midtown Manhattan sees the 4G indicator, experience the slow download speeds (1Mbps, if that), and wonder what's so great about "4G."
They are starting to advertise "4G LTE" here and how great it is, but to me that makes it even more confusing.
So, the standards organization says it's ok to call HSPA+ "4G" and that somehow is a trick by AT&T?
If you haven't signed up for data via AT&T, most times it will show 4G because LTE is reserved for paying customers.
