Hi Everyone, Can people comment on the coverage and performance of AT&T 4G (HSPA/HSPA+) and 4G LTE coverage for the iPhone 4S and iPad 4G LTE? Is it any good? I have a iPhone 4 and it sucks royally in Alexandria, VA. I'm not sure if I get HSPA speeds but many times I get dropped calls and drop outs while streaming music. Is the experience been very good with the improved antennas and 4G HSPA+ & 4GLTE?
