I am having the same problem! My iphone 4 will "time-out" when receiving a text while talking on the phone. Also, the 'ring tone' for the text will play while I'm talking which is very annoying. The iphone seems sluggish and unresponsive - a lot slower than before. Is there a way to fix this? It was such a great phone before the upgrade!
