Can I add a sim card slot to the iPhone 4 CDMA?

Hi, my friend gave me his old iphone 4, but it's on verizon, and I am on T-Mobile, so I was wondering if I can access the iphone's internals and create a sim card slot. I don't really care about looks, I can hide it in a case, I just want to upgrade from my crappy LG. Any help is appreciated.

You are trying to compare Apples and Oranges. One is a CDMA phone (Verizon) while the other one (AT&T, T-Mobile) is a GSM phone. They do have different hardware. So it is not as easy as cutting a slot in the case, the SIM card reader will have to be connected to something that is not supported by the CDMA version.

Contact T-Mobile they can assist you with a CDMA account now.

I don't think your idea would be possible - IIRC the case has significant differences compared to the GSM model so trying to shoe horn a GSM board etc into the case will likely not work.

But couldn't I just add it onto the back with tape and cover it up with say a case?

No. You are talking completely different phones in somewhat similar cases.
