Hopefully Tom was just trying to emphasize that he was a "MAC" user, but honestly, anytime I see someone claim to be a Mac user but write the product name as "MAC", red flags go off... Personal experience: No dropped calls. As expected, there is a hit on performance (bandwidth) when testing download/upload. I go from ~3mbps / ~1500mpbs (via Speedtest app) to ~2mbps / 1000mpbs. This is north of metro Boston. I know there are areas with much weaker signals. I visited California (Lake Tahoe) and found the area a total a hit or miss with AT&T. I would never buy an iPhone (or any phone) that was tied to AT&T. I have a feeling that a lot of people bought the phone first without checking how good/bad AT&T service is in their area...
