If your 3G phone is both GSM and CDMA, then you can't do anything about it. You would just have to use it on GSM carriers.

Will CDMA sim will work in WCDMA mobile?
There is no such thing as a CDMA SIM card.CDMA is a technology which doesnt use SIM cards.And WCDMA is evolved from gsm and uses SIM cards for 3g.
Can you put the CDMA sim card to the gsm phone?
CDMA and GSM are Radio technologies and mobile Phone is just an Antenna to receive these Radio Signals. Since both the technologies work on different frequency range and has different modulation shemes therfore the mobile phones for both are different.Apart from this 3G tehchnology which is combination of both GSM and CDMA (WCDMA) is compatible with both GSM and CDMA. So a 3G mobile can serve for both GSM and CDMA radio signals.SIM (Subcriber Idendity Module) is consists of Credential for network authorization. Since Both GSM and CDMA technologies has different Authorization functions and parameters hence both SIMs are different. Note: In CDMA technology SIM is often called as RUIM (Removable User Idendity Module).CDMA uses Different Frequencies than GSM. CDMA also does not require a SIM card.Now some companies do provide SIM cards for CDMA connections also, such as Reliance communications and TATA Indicomm in India.CDMA can hold more calls per channel on their towers, while GSM drops alot of calls. That is why people are always complaining about T-Mobile and At&t dropped calls. GSM is used internationally while CDMA is mostly used in the domestic United States. CDMA carriers are Verizon, Alltel, Sprint, Cricket....while GSM carriers here in the U.S. are T-Mobile and At&t.
Will Verizon wireless become a carrier of the iphone 3G?
No. but...Verizon made a deal with Apple to end the iPhone's exclusivity to AT&T in March 2011. There was a problem though, iPhones were built for GSM networks (AT&T), and Verizon was a CDMA network. This required a new antenna. Apple never made an iPhone 3G with the CDMA antenna sadly; they did make a CDMA version of the iPhone 4, though. Then, when the 4S came out, the phone had both GSM and CDMA antennae in one phone. So, in the end, Verizon is a proud seller of iPhones, just not the original, 3G, or 3GS.
Can you switch from a 3g iPhone to another 3g iPhone without having to activate the other one?
Only if the iphone is a GSM phone with a SIM card... Otherwise if it is CDMA then no, you have to activate the other iphone.
