Is there any difference between the iPhone 4s GSM and CDMA?

I'm talking about the iPhone 4S not the iPhone 4!

Well sprint ( i think its cdma don't cut my head of its the other! Lol) But sprint is pretty slow the iphone 5 has lte integrated so once sprint gets that all up and running itll pretty good (i hope)

Gsm is att, you can talk and use the web at the sametime and its a faster iphone.
Cdma is sprint and verizon, you can't talk and use the web at the sametime and its a slower version iphone 4 and 4s
