I received iphone as gift. We later learned we could not put it on our business account. What a pain when you own your own business. Then after hours with ATT and apple they tell me I cannot use the same number. I have my number with all my customers and my 4 children and their school. Then as final insult the ATT/Cingular customer service person was speaking to the business person and somehow forgot to put me on hold and I heard their "rude" conversation concerning my desire to keep my same number.
