Welcome to CSR Nation
I am still learning about all my iPhone can do for me. Obviously using the contacts is a great place to have all those numbers and emails that we must have at our fingertips today.
I use the iPhone to take pictures/scans of exhibits at depositions when I am not allowed to take the exhibits.
Today I discovered a new use that I really love. I am sitting here editing and I am going to have to make a run to the FedEx box later. My FedEx driver is prompt. I need to make sure I don't lose track of time and miss him/her. I thought, I wonder if I can ask Siri to remind me to go to the FedEx box at a certain time. I tried it and it works. Loving it!!! I am kind of new to smart phones so this may be an obvious one, but I liked it so much I thought I would share.
