So speedtest.net shows my D1 dload speed at 360 kbps while my friend's Atrix running the HSUPA update dloads at 2400 kbps.
When we move to real webpage browsing my D1 running SS 5.2 (2.3.3) will load any webpage faster than the Atrix running 2.2.
The iPhone 4 is even slower in non-flash websites.
I cannot attribute this to 2.2 because the DX running stock is faster than all of the above.
What's going on?
