Just recieved my vibrant this morning, its so awesome, dare i say, Iphone killer? Anyway i have a few comments and some questions as well. Question 1. This is the first super smart phone (1ghz) i've used. is a task killer still necessary or atleast good to have? Furthermore, were they ever? Question 2. Is there a way to prefent the keys on the bottom of the phone from lighting up when in a game or application? Question 3. What class SD card should i get for this phone? Ill definately be doing pictures,video, and games. (im guessing no less than 4) Question 4. apps to SD, do i have to root? ___ Now for my comments Comment 1. I have not had any problem with my keys on the bottom being unresponsive. Comment 2. I have not had a problem with the GPS or navigation. It found my location to 15feet within 10 seconds, I was connected to 2 - 4 sats judging by the gps app. Comment 3. Awesome phone. Comment 4. We had better get 2.2 and 3.0 and beyond.
