is there any android phones that are bundled with nice data usage packages?

Nyan, actually the three telecom operators do provide phone packages. You can spend a certain amount of money to get a phone and a phone/data package is included. You know, they provide phones in different prices. It's totally up to your budget.

I personally suggest you buy phone and package from China Unicom. It supports WCDMA, a popular mode in most countries in the world. You'd better visit any branch and ask the salesman to make an introduction for you.
