I am thinking of making a program for the iPhone. I have done other platforms but this would be my first iPhone program. Here is what I want to know.

1)Is there a way to know if the iPhone is on wifi or edge? Or a way to know if you are in range of a hotspot?

2)UIKit... Is there a way to make the black bar on the bottom of the phone and iPod program... the one with five choices. It is also in the youtube app.

Here is what I want to make... I don't know if any of you all have ever seen "Digimon" but something like that. You have your own partner creature who lives in a digital world. You can raise and fight him and such with other iPhone owners who use the program. There is a "real world" and "digital world" and the only time you can switch between the two is when you are connected to wifi. The idea being that wifi is the key that opens the gate between the two worlds.

Here is a basic screenshot of what I want my program to look like.



I am going to have communication be e-mail based. You send messages to other users kind of like you would an e-mail.

Can anyone answer those questions. And on that line... does this sound like a cool program to make?
