INTERNET QUESTION

You data package includes internet connectivity. So you don't need WiFi to get on to the internet. You can get on the internet over the cellular network (3G or EDGE).

i wouldnt say "no matter what", but it would be anywhere you have a signal, you SHOULD be able to get on the internet via AT&T's network, yes.

Wi-Fi has nothing to do with the AT&T data plan. Wi-Fi is the same for the iphone as for any computer.

The AT&T cellular network provides unlimited data usage where available. This is not wi-fi.

You can look at Apples web site and AT&T's web site to learn more.

The iPhone has access to 2 kinds of networks - WiFi and Cellular.

Wifi is like home or work and is just your local network that then connects to the Internet via Cable, DSL, T1, etc.

You can use your phone's WiFi to get on a WiFi network, but if you don't have the password you are stuck. Also, WiFi is only good in WiFi area (100Ft), so when you leave work, home or starbucks, you have no WiFi.

iPhone also has access to Cellular data networks - both 3G and Edge. 3G is faster, almost like on the Internet at home or work. Most anywhere you have cell coverage and can make a call, you have Internet access. Sometimes you are on the slower Edge network.

The ATT data plan is for this Cellular data access provided by ATT. So you can usually get online just about anywhere. WiFi is generally faster and uses less battery, but you need to have free WiFi nearby to make it worthwhile.
