This is interesting. Apparently there is a problem in some places with iPhones and dropped calls. So much so that the people at the Apple store are telling people that the dropped call rate is 30%. This seems incredibly high and that most people would find this unacceptable.

Also, the fact that The Apple store seems to shrug this off as problem that AT&T needs to address is astounding. It may very well be true that it is an AT&T problem, but the Apple folks should spearhead the effort to resolve this for their customers. Especially if, as it appears to be the case, the iPhone is more prone to dropped calls then other phones.

The article doesn't mention other phone, but the comments section does include some anecdotal evidence indicating that other phones don't experience similar drop ratios. Whatever the case may be, AT&T and Apple should get together and find a solution to lower the rate.
