I have noticed, even when I am not on HSPA+ (by looking at AT&T's HSPA+ coverage, and by some debug tools) the iPhone still reports "4G". I think this is Apple's fault, as It reports "4G" even when I'm on standard 3G towers, with speeds at like 3-4Mbps. When I go into town, where there are REAL "HSPA+" towers, I have seen stuff around 10 - 12mbps. Why does Apple report your on "4G" even when your not on HSPA+? My brothers Android switches down to just "H" instead of "H+"
