As you probably know already, the iPhone 5 is taller than the previous iPhone 4S and iPhone 4. When I first heard about the change is size my first thought was how long is it going to take to update all my apps to work on these devices.
Turns out that so far it hasn’t been hard at all. I have just had to create a new Default.png to cater for the iPhone 5 and the rest is done automatically.
The new default image is 640px wide and 1136px tall and needs to be called Defaultemail@example.com.
One thing to be aware of is that as much as this process is very easy, it might not work for every single app as some apps have positions and layouts hard coded. The apps that have standard layouts without hard coded values tend to be the ones that benefit from this automatic upgrade.
