I earlier discussed the pain iPhone 3G users are feeling with regards to the 3G network and connectivity. Since then the issue hasn’t faded, and the 2.0.1 software update did nothing to fix the issue.

In fact, more and more media attention has focused itself on the issue.

On Tuesday, Richard Windsor, an analyst with Nomura Securities chimed in. In a research note, he said:

“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.”

Someone hasn’t been reading iSuppli’s teardowns if he isn’t 100% certain Infineon is the supplier. At any rate, if it’s a chipset problem, it may be difficult to fix via a firmware update.

Of course, Windsor is the same analyst who last year speculated that the original iPhone’s screen would begin deteriorating over time, after three to six months.

On the other hand, it’s not like I haven’t seen issues like this before with other devices, including pre-released devices (I work in the mobile industry). I can’t go into details, but I’ve seen issues like this fixed with firmware updates. I will, however, also attest to the fact that the AT&T 3G network is spotty at best.

Even on other devices I’ve seen switching back and forth between 3G and EDGE, so this behavior doesn’t surprise me. If the chipset is the issue, based on past history, I’d expect Apple to do right by their customers. At least, as an iPhone 3G owner who has noticed no signal at times when a Palm Treo 750 a few seats over was doing just fine, I hope so.
