You're lucky. I exchanged my first one 2 days after getting it. I had the antenna issue when holding it, had it on the new phone, and I still have wifi issues with my Apple router at home. The employee at the genius bar actually gave me scotch tape to bridge the antenna. It didn't work. When I got home and used some electrical tape and finally fixed the problem.
