Image via CrunchBaseiPhone: Great Device, Lousy Telephone? - PCWorldIf you have an iPhone, this experience may be familiar: Your phone shows only a bar or two, and either you can't make a call or the call you do make is so scratchy and garbled that the person you're calling can't understand what you're saying. Meanwhile, right next to you, someone on a different AT&T phone connects without a hitch and chats away happily. I decided to informally test whether there's a solid basis for that common gripe. My findings: The two iPhones I tested had lower rates of connecting successfully and had poorer voice quality in AT&T low-signal areas than did two non-Apple AT&T phones that I tested under the same conditions.
I tested four phones on AT&T service in two cities over three days. I drove around San Francisco and Los Angeles comparing the performance of the iPhone 4 and the iPhone 3GS against the performance of the RIM BlackBerry Bold 9000 and the Pantech Impact in voice calls placed at roughly the same time from areas where coverage from the AT&T network is less than optimal.
What I found was surprising. Calls on the iPhone 4 and iPhone 3GS failed to connect or dropped in midcall far more often than did calls on the other two phones, and the iPhone calls that connected successfully sounded marginally worse than calls placed with the BlackBerry and Pantech phones.
