A Swedish technical magazine says problems some users are having with the 3G iphone probably result from a hardware problem introduced during mass production, reports The Associated Press in a story in the Seattle Post-Intelligencer.
This San Francisco Chronicle story delves into the frustrations users have been reporting.
Enginnering weekly Ny Teknik based its conclusion on tests run by unnamed experts that showed some handsets' sensitivity to third-generation network signals doesn't meet the 3G standard.
It says improper adjustment between the antenna and an amplifier that captures very weak signals from the antenna could lead to poor 3G connectivity and slower data speeds.
News.com's Tom Krazit has asked researchers at Stanford University and the University of California-Berkeley to try to duplicate the findings. He's awaiting a response.
Meanwhile, a Reuters story puts the blame on an Infineon chip, reporting that Apple plans to fix it with a software update.
