What should I do about problems with iphone 4?

Hi. I have also been using the iphone 4 and I'm also facing a weird problem in iphone 4, it is having a signal strength problem. The depth grip problem also occurs in iphone 4. The iPhone 4 rear camera has taken some spectacular outdoor shots and even produced HD video good enough for music video. iphone 4 does have some other issues. The image criticizes it a little too much. This is also having a display, drop it from average height and proximity issue. All the issues which are genertad in iphone 4 is solved with iOS 4.01. I have also faced one problem with my iPhone. It's so frustrating because I am constantly putting people on hold or speaker phone or just hanging up on them. I think you should do the same or a better option would be to contact the customer service provider because they can guide you the best possible way.
