Welcome to the board! I'm too tired today, so I can only afford to write a short answer.

The components in Nokia's cell phones come from many manufacturers, including Texas Instruments, RF Microdevices, TriQuint Semiconductor, International Rectifier, Intel, among others.

If the world decided to follow and eventually changed to QCOM's CDMA

There's some confusion here. GSM has 56% of worldwide mobile subscribers, while CDMA only has 11.7%. There are no significant differences in voice quality and spectrum efficiency between GSM and the current generation of CDMA. The world is not going to switch to Qualcomm's second generation CDMA system any time soon. As China Unicom demonstrated, it is simply not economically viable to do so.

As for third generation systems, there are really five flavors, as defined by the International Telecommunications Union (ITU) as part of the IMT-2000 standard:

- IMT-DS Direct Spread (formerly known as WCDMA)
- IMT-MC Multi Carrier (formerly known as cdma2000)
- IMT-TC Time-Code
- IMT-SC Single Carrier
- IMT-FT Frequency Time

The first two are based on CDMA, IMT-TC is a combination of CDMA and TDMA, IMT-SC is TDMA, and IMT-FT is a combination of TDMA and FDMA.

Nokia, Ericsson, NTT DoCoMo, SK Telecom, among others, support IMT-DS as the 3G upgrade path for GSM, TDMA and NTT's PDC network, while Qualcomm pushes IMT-MC. I doubt the other standards will ever get implemented. Because of GSM's huge install base, most believe that IMT-DS will get the overwhelming marketshare, but Qualcomm bulls believe that Qualcomm will receive royalty fees no matter which standard mobile operators choose. I think the royalty issue is still unresolved and it is too early to tell, simply because Nokia, Ericsson and NTT DoCoMo started developing WCDMA long before Qualcomm started cdma2000 research. Who pays whom and how much are still unknowns. Besides, 3G will not be commercial available until several years later. GPRS, HSCSD and EDGE systems are where the money is.

Nokia's business is not just making/assemblying cell phones. Nokia is into wireless infrastructure, internet infrastructure, fixed wireless, firewalls, DSL, TETRA systems, etc. The best place to start reading up on Nokia's business is its website:

Hope I haven't caused too much confusion.
