IPhone :: Unable To Find FaceTime

I just got a replacement iphone 4. On my first iphone 4 the microphone would not work on speaker phone or face time. I’ve had my new replacement phone for two days. I tried the microphone on speaker phone and it worked. I tried to connect with face time to my wife’s iphone 4 tonight. I placed a call and after I connected I looked and there is no face time button. I had my wife call me and push the face time button (yes I know it’s not really a button) on her phone it displayed connecting but it would not connect to my phone or show on my phone that there was a face time attempt. We are both on wifi and have a good cell signal. I tried to do face time through the phone contacts and the contacts icon.

I have 4.0.2 installed.
