Nope, I may have issues I cannot see or notice easily, but no dropped calls, good reception and once again in areas I did not get it with my 3GS, if you think I would buy a sim free iPhone and keep it if it did not work...well you would be very off the mark, I like Apple products, but I want to use them, not look at a phone knowing two plastic cups and a piece or string would have better communication properties. So you are wrong, some of us have less issues than others, that simple.
