Hello everyone. This is my first time on here, and I need advice. I'm not real tech savy, but can usally navigate most devices. Enough to get by anyway. What I need to know is; Walmart is selling Iphone 4 for $147, AT&T for $199. I plan on buying 3. AT&T says they will set the phones up for us. What does that mean? Are they so complicated the average person can't operate them. I would like to save the $156 dollar difference between AT&T and Walmart. Does anyone know of a reason to get them at AT&T instead of Walmart. I appreciate any help/advice you can offer.
