We've been hearing from many of you who bought a shiny new Inspire 4G that there appears to be an issue with the device upload speeds.� While AT&T is busy working out the kinks in their HSPA+ network, getting backhaul in place and pouring the magic 4G dust into the wires, most of us with an Inspire 4G are still using the 3G HSPA network.� HSPA is broken down into two parts -- HSDPA (download) and HSUPA (upload).
The Inspire 4G is not HSUPA�capable, according to AT&T.� No conspiracy.� No rumor.� Just the answer, straight from the source.
This explains why most of us are seeing fast 3G download speeds, but no-so-much on the upload side.� I had a bit of a play with this myself last night, and see the same thing -- download speeds around 2 Mbps, and upload speeds around 200 kbps.� You can see above what our (and TiPb's) own Jeremy Sikora is seeing for speeds in Chicago.� He also notes that upload speeds on his iPhone 4 (which is HSUPA capable) are about twice what he sees with his Inspire.
While it's not the news most of us want to hear, it does clear up the confusion.� Thanks to the folks at AT&T who took time to answer our questions.�
