I don't mean a book that says: "This is what it should be". Or "in college they told me".
It's easy to critisize another, but can you equally back up your claims that Jason is wrong? Where di you get your benchmarks?
Now, AT&T claims on their own site- be it for HSPA; that they have 100 - 200 ms latency. Now, anyone who has ever worked a network, or driven in traffic for that matter knows that there is congestion and this could have a huge impact. Ever had a website timeout on you before? Let me give you an example. AT&T order your Iphone page. What a disaster, but they have a huge backcone and server capability... What happened? Too much network congestion... Ever tried to order concert tickets or any other event, at noon, online the minute they become available? Same thing happens. So why would a few million smartphone, all trying to connect to the same tower at the same time, not experience the same dilemmas?

So, testing at 3 o'clock in the morning in rural areas is not a "valid" benchmark, IMHO.

Besides "4G" is being loosely used. Most being accepted as 4G, because of the band it uses, whihc is not the same as 3G (from what I understand).
