We reckon this topic's going to heat up immensely as O2's EDGE and iPhone rollouts cross paths in the next few weeks, but at the moment, it's really only applicable to the privileged few sporting unlocked examples in their European pockets: what happens when you're covered by GPRS, not EDGE? AT&T's done a pretty good job of blanketing its entire coverage area with the so-called 2.5G tech, so we really haven't had an opportunity to test GPRS operation of the iPhone (thank goodness) here -- but tech.am is reporting that an unlocked unit on Vodafone Spain still shows the "E" symbol in the status bar with nary an EDGE signal to be found. Did Apple get the memo that the "E" actually stands for something?
