Gigaom reports that the multiple connectivity issues faced by new iPhone 3G owners could be due to issues with the Infineon 3G chip.
Since the launch of the iPhone 3G, there were complaints related to poor reception and low speeds. AT&T was blamed - but the company denied of any issues with its network, while adding that they would look in to all the complaints on a case-by-case basis..
With similar reports started coming in from other networks as well, looks like AT&T might have been right after all. The latest news is that the Infineon 3G chips used in the latest edition of the iPhone could be the cause of these connectivity issues. Richard Windsor, a Nomura Securities analyst quips, "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." If this indeed turns out to be an issue with the chip, it would be the second major reported chip failure this year. Nvidia grabbed the headlines a few days ago when some of its laptop graphic chips were found to be faulty owing to poor packaging.
To make things worse, these kinds of faults cannot be fixed by a simple firmware flash. It's not clear if Infineon makes these chips themselves or outsources the manufacturing to others. Product recall looms large? Let's wait and watch.
