The Samsung Infuse 4G has made it’s way through the FCC Approval process with flying colors. Originally dubbed the Stealth V (seriously, who comes up with these names?) the FCC has certified the Infuse for AT&Ts 850/1900Mhz bands. The Infuse received Bluetooth certification last December and is also cleared for use with GSM/GPRS/EDGE/WCDMA and HDPA. AT&T has already started marketing the Infuse as part of their 4G lineup, which includes the Motorola Atrix 4G and the HTC Inspire 4G.

As we saw at CES last January, the Infuse 4G is based on the Samsung Galaxy S design, with a huge 4.5″ Super AMOLED plus multi touch screen, 1.2 Ghz Hummingbird processor, and an 8MP rear facing camera (along with a paltry 1.3MP front facing camera for video chat). With two cameras and a huge screen, it’s amazing that the Infuse packs all that into what AT&T calls the thinnest device they’ve ever carried.

But even though AT&T is boosting their 4G lineup with a series of impressive handsets, are they cutting off their nose to spite their face? Users have complained recently that AT&T has been throttling the Atrix’s 4G upload speeds, while AT&T has responded by implying that the HSPA+ and LTE option isn’t even turned on yet. Now this may only be solely confined to the Motrola Atrix, with other 4G phones having already been cleared. But will users be wary in diving into a 4G phone until AT&T has actively begin supporting what their marketing materials have been touting?
