I'm in the uk and data comes as part of all iPhone plans, but if you've bought the handset either add data to you plan or get it removed from your account network side and just use WiFi. This would be advisble due any smart phone. Paying per megabyte can be costly.

A smart phone allows for voice and internet connections. As such you will need a voice and data plan. Cell phones like the iPhone automatically come with both, you cannot get one or the other. If you plan to do a lot of internet surfing on the phone you might consider an unlimited data plan, otherwise you might get hit with large overages.
AT&T does not allow for any iPhone after the original one to be active without a data plan. The only option would be to unlock it and use it on another carrier that uses SIM cards. You'd also have to search how to alter a SIM card to fit into the iPhone 4's MicroSIM slot.you can unlock it at unlock att .com and the sim card can be cut to fit in the micro slot all you do is go to any iPhone store they do it for free!
* No, you don't have to switch plans. You keep the same Voice and Text plans you had before. However, if you didn't have an Internet plan in your previous telephone (call it Blackberry or any others), you will have to add to your plan the Internet and data for 20 dollars a month (this is for unlimited used within USA) This plan can be cancelled, but hey whats the point of having an iPhone and not be able to use the Internet on it?
Yes, you can have a 3G and 4G iPhone on the same mobile plan, as long as the carrier supports both types of devices.

It's important to check with your carrier for any specific compatibility or plan requirements.
Yes, for any cell phone you have to pay for the data usage. Definitely get an unlimited plan, as the rates for data usage are expensive. Or if u want to unlock your iphone u dont have to pay for the internet as long as u have wifi in the place that u are in.
