The "magic spot" "problem" does not affect the Edge band for this particular user, in this particular location, on this particular day, in this particular phase

The "magic spot" "problem" does not affect the Edge band for this particular user, in this particular location, on this particular day, in this particular phase of the moon. Antenna design is black magic on the best of days. When you mix in all the variables at play across three million phone users around the country you get lots of irreproducible results. What I find myself wondering is: Sure, closely coupling a big bag of saltwater (e.g. me) to the phone may [1] tend to reduce the antenna efficiency relative to leaving the phone alone on a table. But can I strap the iPhone into some sort of specially-designed case that's designed to increase the antenna efficiency? [1] EDIT: This word used to be "will", but having just read Anandtech's fun analysis of this "problem", I am reminded that what giveth in one waveband taketh away in another: Anand improved his WiFi signal power under certain conditions by gripping the phone.
