iPhone to Atrix newbie


Hello all, I have been an avid iPhone user for 4 years. I decided to try a Android phone, the Atrix 4G as Costco had a special going this week and I am within the upgrade window. So far I am stumbling through this new system. I have a few questions that I will post to the correct section.
I am retired from the military, retired supervisor for a government employment services agency. Now a full time student and small business owner.
I live in Southern California, the land of outrageous gas prices even though the oil we import comes in right here. Go figure! Looking forward to some advice from those that are knowledgeable on this phone/system.
Thanks in advance...
