Analyst: 17% of Verizon Customers Waiting for iPhone

Whats the chances of a Verizon IPhone being released/announced on June 7th at the same time as the new AT&T IPhone?

Wrong - W-CDMA is a GSM adopted spec. This is AT&T's current standard.

Don't criticize people without knowing what your talking about. CDMA and GSM are two entirely different modulation schemes with two entirely different signal space representations. They have different noise immunity characteristics. They require two different sets of hardware to implement (either on separate ICs or a hybrid chip). Depending on the hardware implementation, it might require two different sets drivers for each protocol.

Saying they are the same thing is like saying IEEE 802.11a/b/g/n is the same as Bluetooth.

For AT&T, like 802.11 and Bluetooth on an iPhone, there's no reason you can't implement both protocols.

What are you talking about? CDMA or W-CDMA? Because I'm talking about W-CDMA which the GSMA adopted. I NEVER said GSM and CDMA are the same. To be clear, let's stop using the generic term "GSM".

Edit: In hindsight I may have simplified things too much, but I was trying to make 2 points. The first was that they are both based on the same base technology, "Code Division Multiple Access" as opposed to the old GSM air interface TDMA "Time Division Multiple Access". The second is that while CDMA had it's strengths, one of the cons was the cost of paying Qualcomm royalties. But I was not saying that "GSM" (or even W-CDMA) and CDMA are the same.

On a side note, I used/sold TDMA in the early '90s. Wow it sucked when it first came out. CDMA as an air-interface was always superior for voice.
