I am switching from AT&T to Verizon and I don't want to buy an brand new phone. Any way to unlock it for Verizon Wireless?

No. You'll have to get a "verizon" iPhone... selling your 'at&t' one after should mostly offset the cost.

Impossible. Case closed. Sell your AT&T iPhone and use that money to buy a Verizon one.

Check Craigslist or the iMore forums for phones for sale. Just make sure that the phone is clean and not reported stolen before you buy.

out of curiosity, can you take a Verizon iPhone 4S, unlock it, and then activate it on At&t? T-mobile?
I understand why you can't go from at&t version to verizon because there is no CDMA component to the phone. Just wondering if the opposite would work.

No.

While the iPhone4S physically has the capabilities - they are all quad band radio equipped - phones made by Apple for Verizon or AT&T are "locked" deep within the OS/radio firmware so they can not be made to be interchangeable.

May i know verzion CDMA or GSM

[Alli]

Verizon and Sprint are CDMA. AT&T and T-Mobile are GSM. (Most European carriers are GSM.) You cannot use any CDMA phone on a US GSM network and you cannot use any GSM phone on a CDMA network.

You are mistaken.
