Bell is using a "Twitter line" that will be open from 10 am to 10 pm Eastern time on December 1st. The first 100 people on the line will be guaranteed the opportunity to buy the phone and have it shipped on December 8th. But those who take part in this experiment (for lack of a better word) will have to tweet out a promotional message for the phone every hour from 10 to 10 on the first of next month in order to keep their place in line. Those who can't be bothered to sit in front of a keyboard all day can simply place their preorder for the phone. The advantage for using the "Twitter line" is that you can be locked in as one of the first 100 in Canada to receive the phone.
