I posted this question in the middle of another thread, but I thought I'd repost this here. Now obviously Apple lacks the same experience as the established cellphone companies like Nokia, Ericsson, and Motorola. Many of these depend on call-related innovations like background noise filtration, increased signal strength, better receptivity, and have proprietary technology to compete with each other. Apple might have the expertise as a computer and media player company, but I'm somewhat skeptical about its cellphone technology. Can anyone comment? I've read some reviews saying that as a phone, iPhone 3G is a much improved product over its predecessor, but that doesn't help. Does it provide anywhere near the same telephone features as its more established competitors?
