Just remember that Apple isn't particularly adept in the RF Arena, and
the iPhone/iTouch/iPad are their only small products that have RF
Antennas, this small. Also remember that some of their Laptops, of past
years, had some serious Wifi Antenna placement problems, and remember
that Wifi at that time was only a Single Band, not a Three Band System,
like the iPhone4.

Lesson: don't buy a cellphone from a company that doesn't know how to
build one (and wants to be in the business of cellphone design without
hiring the knowledge required).
