I have some questions on CDMA vs GSM. A lot of the information I have read on the internet across a bunch of sites say that, in general, CDMA real world data transfer rates is faster than GSM real world data transfer rates.

Is that true? Because AT&T calls themself the "Faster 3G Network available" but if GSM is (by nature) slower than CDMA, how would that be possible?

With the R-UIM cards, will those be out in the USA anytime soon? If not, why are they not/will not be in the USA?

Why does a 850MHz spectrum go into buildings better than a 1900MHz spectrum? What does Verizon operate on? (I read VZW is on a 800MHz spectrum, so does that mean they have better in-building service?)

Why is 3G not everywhere where service is offered? I live in MT and much of MT is not in the 3G network, oddly. I have VZW

What makes a phone faster than a different phone built in the same year? Do they all use the same Qualcomm provided chips or no?

Why does a company, like VZW, provide free calling and texting to other VZW customers, but not to any other company?

What is the whole deal on Data Transfer Caps that the FCC is pushing to Cell Phone Providers? Why can't I have true unlimited internet? Like VZW pushes a 2GB or 5GB transfer cap? I understand next to no one will ever hit that, but why can't I have true unlimited/unmetered data transfer?

I may have more questions in the time to come. I'm really interested in how Cell Phone Providers work
