3G is marginally faster, but edge is more stable, i had both edge and 3g. Edge doesnt drop the signal, 3g does if you move sllighty, although edge doesnt support video calls as 3g does.
For the iPhone, the cool thing isn't the EDGE support (or lack of 3G), it's the wifi that is good. With the free use of 7500 hotspots, that should be better for the majority than EDGE.
That's very true. My point was that lots are complaining that the iPhone is terrible because it only does EDGE and not some 3G technology, but for many it won't really matter as there'll be wifi available.
