Maybe I'm missing something, but I can answer calls when the phone is locked. I just drag the Answer button into the ring and I'm connected to the caller. When the call ends it goes to the unlock keypad screen.
I use "No Lock" from the Market. It provides a widget that you press to toggle having the lock ring active (or not) when you turn on the display.
I'd start in here http://androidforums.com/rezound-al...l-things-root-guide-updated-12-29-2011-a.html But careful about removing Sense. There's a thread in the Root section about removing the lock ring and someone not being able to answer calls. Good luck.
WidgetLocker is such an amazing app, and the dev, kevin, is really responsive on the boards.
the ONLY thing i have found is that it does not replace the call answer swipe part that you are talking about. but for the lock screen, it's amazing.
I looked up widgetlocker in the market, and I'm a little wary because of the reviews. They seem to run about 50 50, and they indicate it's still a bit inconsistent right now.
Not ready to pay $2.99 if it appears that unstable now. Maybe when more of the kinks are worked out.
I've had WL since it was $.99 when it first came out in the market, back when i had my DInc, brought it with me to the DInc2 and now on my Rezound, and I will continue to port it to further devices, i trust in it that much.
