The status bar has grown, so parts of my interface get cut off. Any pointers on how to fix this (e.g. using autoresize masks, etc.)?
I use Interface Builder for the UI, so everything is .xib's.
You generally handle it with autoresize masks, or if you have custom views you can deal with it in the layoutSubviews method.
The simulator has an option "Toggle In-Call Status" you can use for testing it out without having to load it on the phone calling yourself.
