Since the same towers are used, does 4g provide a wider, or stronger (or less strong) signal compared with a 3g signal coming from the same tower? 3g coverage is weak where I live and I'm curious if it will be the same when I get my EVO.
Yes, but since 4g uses a completely different frequency than 3g, does it's signal penetrate buildings better or carry farther when compared with a 3g signal coming from the same tower?
ah I see what you're saying scary! He's right too. The big change that happened when over the air TV broadcasts went from analog to digital a couple years back was that you wouldn't have the "static" anymore. You either got a signal or you didn't. Good point.
I'm a little slow on the uptake, but I thought WIMAX (4g) is broadcast on an entirely different frequency band than EVDO (3g). And that because of this, 4g signals suffer less from attenuation and, therefore, provide improved range and better coverage within buildings (btw, that's the extent of my radio tech knowledge ). So... theoretically, if I'm standing still in an area where Sprint has both 3g and 4g coverage, and have a 3g phone in one hand and a 4G phone in the other hand, shouldn't the 4g phone receive a stronger signal?

You don't get static, but you can still have signal gaps/drops even with digital transmission.
Wimax is for data only so don't overlook that. Both 3G and 4G are subject to interference and obstacle instruction (building penetration) as well as tower location. Signal strength, in essence, varies more by what's stopping the signal from reaching you than the actual signal. And though it's already been pointed out, a reduced stregnth in signal may not affect what you see/experience, reduced signal can mean data interruptions. That's why calls drop and digital pictures have hiccups and freezes. So it's not entirely true that a low signal would result in no performance reduction - only that a reduced signal reaches a point where it no longer becomes a continuous signal.
Wimax towers generally are much higher than traditional 3G cell towers because the site emits a much higher radiation footprint and is therefore usually code-required to be further removed from people (higher). The height is one reason you don't see Wimax towers more than you do - local codes usually have height restrictions.
EVDO / 3G is in the 1900 MHz range
WiMax / 4G is 2.3 GHz, 2.5 GHz and 3.5 GHz
Typically the higher the frequency, the better the penetration, and less attenuation.

Wimax's real advantage is that theoretically it's signal is at such a high frequency that it is fades less.
