// How to make a universal binary
// Step 1: Create an iPhone project
// Step 2: Go into Target Settings and set arch to arm6 and arm7
// Step 3: Set base SDK to 3.1.3 and under the deployment tab set device family to iPhone/iPad
// Step 4: Create an iPad NIB from an existing NIB and then add the following code to load a different NIB if you set the deployment version to iPhone SDK 3.2 (To target the iPhone you need to use 3.1.3)

// Settings notes
// Base SDK = iphone devise 3.2 
// Target Devise Family = iPhone/iPad
// iPhone OS Deployment Target = iphone devise 3.1.3
