iPhone 3G connection woes may be due to chipset: report 3:33 AM EDT August 12, 2008 LONDON (MarketWatch) -- An immature chipset solution from Infineon Technologies AG may be at the root of reported connection problems with Apple, Inc.'s 3G iPhone, Nomura analyst Richard Windsor said in a note to clients Tuesday. He said some iPhone users are having trouble getting a 3G connection and hanging on to it. Hiccups reportedly include a high incidence of dropped calls, switching onto the slower EDGE network while the device is stationary and loss of reception while in good coverage. "We believe that these issues are typical of an immature chipset and radio protocol stack where we are almost certain Infineon is the 3G supplier," Windsor wrote. He added that because the problems are likely to be embedded in the low-level software and the chipset, a firmware upgrade from Apple is unlikely to fix the problems, giving rivals Nokia Corp. , HTC and BlackBerry-maker Research In Motion some time to get their user experience up to the iPhone standard.
