iPhone makes me hang up on Customers

I use Vonage for the store toll free number.  Last week I started having Vonage forward calls to my cell phone.  One small problem: I hang up on every customer.

The most annoying thing is when a call comes from someone not in my contact list the button to the left is ‘hang up’ and the button on the right is ‘accept the call’ or something to that nature.  I instinctively swipe my finger from left to right like I do when I turn on the iPhone.  Unfortunately this hits the ‘hang up’ button before it gets to the ‘accept the call’ button.

I know it is simply a matter of getting used to the location of that button, but if you have tried to call and got dropped, I’m sorry. :(

Apple should have thought this through a bit better, though.  I am sure I’m not the only one who instinctively swipes his finger on the screen to turn it on. Maybe there is an option to fix this problem… checking…  nope, doesn’t look like it.  :(
