All upgrades absolutely will involve QCOM because of their CDMA patents, regardless of the version. The article is dated. If you or anyone else is really interested in getting a specific question answered I suggest you check out SI Coming into Buy Range or the Moderated Thread. Sorry I can't link. There is so much FUD and spin on these issues. I am not technically qualified to address tech specifics although I've read virtually every QCOM thread almost daily since June 1999.
