WB is right. My prepaid smartphone uses only 3G. My phone has 2G and EDGE features but they somehow got turned off by AT&T.
2G/EDGE works just fine on all three LG Thrives I have albeit downstream and upstream are atrocious. Perhaps you just have good 3G signal where you're located so you never drop down to 2G/EDGE.

I can bet that the Infuse is also 3G capable, 2G and EDGE capable too. That's how postpaid phones like the Infuse can roam on other carriers' network that may be 3G or EDGE only. If AT&T did not turn off the 3G feature of the Samsung Infuse, you may be able to use the Infuse on a prepaid plan. All it takes is for you to test it out. The other possibility is that the 3G setting could be in the GoPhone SIM card, so that it would be the SIM card that enables the prepaid plan to work.
As far as I'm aware, the "4G" Infuse still uses 3G technology. A pumped up version of 3G but still 3G nonetheless. I don't think there'll be any problems with using the Infuse on GoPhone (of course I could be wrong). If someone has an iPhone 4S on GoPhone with data packages working, that should be confirmation enough.
You are probably right. I have an LG 2G/EDGE phone and I have noticed that the signals are no better than the 3G signals on the LG Thrive. I have yet to go to a place with poor 3G signals so that the Thrive will drop down to 2G/EDGE.
I'm of the opinion that 4G mobile devices can down shift to 3G, EDGE and 2G. It would be silly to think that 4G devices can only run on 4G. Because 4G is available only in a small number of markets, AT&T would therefore want customers to downshift to 3G where only 3G is available.
+1 on the iPhone 4S as confirmation of a 4G device used as a GoPhone.
