Audiovox PPC-6600 / PPC-6601 / XV6600 (HTC Harrier)

I need to have a phone on which I can leave myself voice memos, such as while driving. Some of these may be up to a minute in length. The feature also needs to be easy to access, with just one or two clicks, so that I can do it quickly and easily while driving. Does this phone fit the bill? How many voice memos, total, can I have on there at any one time? Is there a limit on the length? Any assistance y'all can give is greatly appreciated.

cheers,

Ben
