That could of course be that the people you know are quite likely limited to a finite number, whereas the Internet isn't. MR is iPhone central - of course people are going to be on here with problems. If there were none of these people it would be a little strange, no? There're only as random as you or I to be fair.
Very true....I know a finite number of people. I am also not surprised to see people report problems with their iPhones on an Internet forum the size of MR. What does surprise me however are the threads that report chronic problems and multiple replacements. There have been a fair number of "chronic" iPhone 4 threads on the Internet that I have read. I guess that I just don't have the patience or brand loyalty that some of these people do....chronic issues and replacements would cause me to switch to a different phone manufacturer...or resort back to the 3GS if its only the 4 causing so many problems. But that is just me.
