i did that thing on google.com/m and just did the iPhonenetworktest.com and it came up as 1764.5 and under says not an iPhone... normal?
Where you on Wifi or Edge?
I got like 1513kbps on edge after changing the setting on google.com/m
and like 2045kbps after the change.
before i changed the setting on google.com/m i got like 128kbps on edge.
But honestly i only think thats on sites that are for design for mobile phones (non HTML) because there is an option on the bottom of the network test to view the site in html and when i clicked on it i got my slow speed again.
