Is there a way to change how you answer the phone? I have a hard time doing the slider thing one handed. Is'nt there just a way to change it so you can hit a button to answer your phone?
The only way to get a different screen is if the phone is unlocked when it rings.
If there was just a simple button you would end up answering the phone while it's in your pocket.
At this time there is no way to change the ICS lock screen or incoming call screen.
Did you look at any of the accessibility functions? There is an option for 'power button ends calls', maybe there is something there for answering as well? I really don't know, just sharing what I found.
