My roommate that I don't know very much wants to sell me his 6 months old BB Pearl for 150$.

My phone sucks and we are both using Telus so I thought it might be a good deal, or not....

He says it works perfectly but I've got no way of knowing. And he might be moving out soon. This guy doesn't look sketchy at all but is there a way I can make sure the phone works.

Thanks guys.
