Went here for an upgrade; it took a total of 20 minutes during my lunch hour, got my new iphone, I have never been at a phone store this short, I have only been a T-Mobile customer for 1 year, I was previously with AT&T for 10 years ! They screwed me over. I switched. I have not had a problem yet. Jenn I believe was her name, was pretty awesome, she even had the nails to match the Pink T-Mobile LOGO lol
