I posted a question before on this site regarding my 8700g not working properly. The thread is: http://www.blackberryforums.com/gene...-sim-card.html
So because my T-Mobile is out of warranty and I can not get it replaced for free, I will need to pay for a refurb one. The cost is pretty high. So for the time being, my cousin gave me her brother inlaw's 8700r. The problem is that I don't want him to know I have it. Long story.
Anyways, I have wiped the BB unit clean and I was wondering, is there a way he or his company will know that I have it and using it? Through the IEMI or PIN????
