Showing MAC address changes on my cell .

Hubby and I drive to the sprint store on Lorain Ave in North Olmsted, I believe my son's phone wasn't working, here's what transpires.

Frank was kind enough to assist and I say wouldn't mind having a new one too! Frank was more then happy to give us 2 brand new Blackberry's at no cost to us and break the current contract, free free free I tell yah, I turn in my old phone and my son's! 
 What a great deal!   

My Brand new cell phone he took out of the box and he put the battery in and did some stuff on his computer and look what my phone has!

The type of cell phone I had Blackberry 9670:
