As tech savvy as I am I’m still have a devil of time pushing the right buttons on my droid. The screen lock only seems to work to prevent me from answering an in-come call. It doesn’t seem to stop the droid from make a call to the last person in the history list. When the lab tech showed up to tell me my butt just call her up is the time I started reading the manual. Boy this thing can do some pretty neat some. Still it feels like assembling a ship inside a bottle. I live to recharge.
