The only application that does this on my iPhone is Safari; it just drops out once and a while for no apparent reason while I'm browsing via Edge or WiFi.
Apple has been great at working out this type of problem in Version 1 products since I started using Apple products. Of these (three Macs, two ATVs, one Airport Extreme router, two iPods and now one iPhone all purchased since last September) a number of them were Version 1 products. I have had less problems with these than most of the established PC products that I have owned in the past. Therefore, I am sure that within a very short time the iPhone will be an even greater product than it is right now.
