Lol dude take your time you have a long way to go.. There is no way you can understand this crazy high tech device in a day not even weeks... Maybe months. Ive had 3 in 3 years and im still learning. As far as MMS goes (picture mail) your MMS (Multimedia Message System) should come straight to your phone I had an issue with this once before and it took 3-5 calls with T-Mobile before they finally got me taken care of. I know you've heard this before but... Even though we are friendly people the Search button is your best friend.
Just my 2 cents...
Oh yeah and welcome to the Blackberry your life has just changed for the better.
