Apple, AT&T look into iPhone 3G connection issues

Numerous reports indicate that Apple and AT&T are investigating a rash of iPhone 3G connection problems affecting some handsets. A San Francisco Chronicle article tells the story of one iPhone user, who claims to have had ongoing connection problems with the 3G. “I was driving down Folsom Street in San Francisco, and I got a dropped call 10 times. I get dropped calls just standing in one place,” said Stephen Yarbrough, a 34-year-old accountant. “I’m extremely annoyed, but I’m hopeful a software update will fix it.” Later in the piece, AT&T spokesman Mark Siegel said that while customer concerns were being looked into, it is difficult to know if they are widespread or related to individual circumstances. “How a device performs in individual situations depends on circumstances like where you are in the 3G coverage, how close you are to a cell site. Things like terrain and buildings all come into play,” Siegel said. “I’m not denying that people are having a less than satisfactory experience, but overall, the phone is doing great.”

CNet staffer Tom Krazit points to an Apple discussion thread on the topic, noting that iPhone 3G users are having trouble connecting, and staying connected, to 3G networks, with the phone switching between 3G and EDGE networks even when sitting still. In addition, Krazit notes that international iPhone 3G users are reporting similar problems, suggesting the issue lies with the handset as opposed to the network. Finally, Nomura analyst Richard Windsor has said in a note to clients that the problem may stem from an immature chipset from Infineon. “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, adding that because the problems are likely to be embedded in the low-level software and the chipset, a firmware upgrade is unlikely to fix the problem.
