For Christmas I wanted a Blackberry, i have the samsung alias. My mom found that it would be cheaper to buy the new Blackberry Tour with an added line to our plan for 10 dollars a month. Is there a way I can switch the new number to the alias and my number to the blackberry. To do this i know i will need to switch my plan to the $30 a month extra. If i can do this will i be able to backup all my contacts if I have them all on my backup assitant online and on the Alias?
