I am developing an iPad application, and I am trying to figure out the best way to decide if a user can connect to the Internet.

In applicat...

The Apple iPad docs say to use UI_USER_INTERFACE_IDIOM() to check if I am running on iPad or iPhone, but our iPhone is 3.1.2 and will not have UI_USER_INTERFACE_IDIOM() defined. As such, this code breaks: //iPhone should not be flipped upside down. iPad can h...
