It appears that the HTC Inspire 4G is suffering from a slower than expected upload rate. Users, for the most part, were thinking that they would be experiencing at the least AT&T’s full 3G HSPA+ network. However, that’s where the problem comes in to play. HSPA has two parts to it. One is for downloading (HSDPA), and the other is for uploading (HSUPA). So what’s the problem? Well according to AT&T, HSUPA is not available in the HTC Inspire 4G. Sad to say, but true nonetheless. I’m sure many of you are will be upset about this, so we want you to sound off in the comments. Have Fun!
