I sent Steve Jobs an email on Friday saying the following: Steve, I have been a loyal Apple customer for 8 years (since age 14) and have been very satisfied with all products up until the iPhone 4. The main function of the product is to make and receive phone calls, and this is very difficult to accomplish. The proximity sensor has given me nothing but continuous problems. I was going to return the phone, but the employees at the Apple Store assured me that a software update would fix this problem. I updated to 4.1 yesterday and still have these issues. In fact, I think that the proximity sensor has gotten worse. I think this is a hardware issue and now I am outside of my return period so I am stuck with this phone, and I use the word phone loosely, for two years. When are you going to come out with a real fix for this problem? Thanks, Then an Apple representative called me today. She asked me detailed questions about the issues I was having including frequency etc. She said that she is trying to gather additional information from customers experiencing this problem for the engineers. She also said she would call me back on Friday and hopefully have more information/a solution. Has anyone else had a similar experience?
