Q: My wife has ALS and no use of her hands and virtually no voice.

My wife has no use of her hands and virtually no voice, she can turn on her iPhone 3G with a Bluetooth device that has a large button connected to it that she can touch with her arm to turn on the phone ready to redial the last number typed in......however she cannot activate the "Swipe to Unlock" feature?     Is there an App or any way I can get rid of the Swipe to Unlock button or replace it with a Large Button she can hit,  we have tried the Security code method with no sucess.

Any suggestions from the experts out there very welcome.    ( There's an app called Nose Dial with two large buttons in the German iTunes store but I cannot get it easily from Canada)  Dave
