Disappointed again

I have now owned three i-phones. They are the greatest gadget i have ever owned! However the I-phone 4 & 5 are the worst phones I have owned. The I-Phone 4 dropped signal on almost every phone call! It became a common joke amongst my friends that the phone would lose signal on almost ever call. When I went into the Apple shop with my 4 they agreed and one of the agents showed me if you hold the phone in the wrong place that it would lose signal. I really struggled to buy the i-phone 5 after owning the 4 and this one does appear to be better for signal strenght. However the new connector than does not work with any of my docking stations etc is a real over sight for apple. Why charge £25 more for the adaptor!
