Will my verison iPhone 4 work in China?

I'm going to China for 10 days in November and I'm worried that my phone won't have service being I'm from The USA. I have Verison and its an iPhone 4. Will it possibly have Internet but not be able to text or make calls. I've heard that it will text but no calls and I've heard that nothing will work, not even Internet. So I'm just trying to get a real answer. Does anyone know from experience or work for verison or something?

Its Verizon & most likely it wouldn't seeing as Verizon is a CDMA network & most international carriers are GSM. I heard that in those scenarios Verizon would lend you a loaner phone while they hold yours & then of course upon return you get back yours.
