Have you tried a post paid SIM in the Samsung Infuse and received data service? So you know the phone's settings are correct for using at&t's data service and it truly is the prepaid SIM that seems to be the problem?
And another possibility - do you have a data feature package on your prepaid account? If not, I wonder if the Samsung Infuse could be subject to the new at&t prepaid requirement for smartphones (no PPU data service), while the 3GS is old enough that it potentially could avoid the requirement. (?) Just a thought as the prepaid smartphone plans are so new that I haven't really seen any indication of how they function yet.
There must be a happy medium somewhere between being totally informed and blissfully unaware.
