I have never seen HSPA noted as being used on my phone.
1x, 2g, 3g, 4g yes, but not H.
Where are you located? I am very curious.
Who is your carrier ISP?
I'm in Oklahoma, USA and get 3g and 4g most of the time until I travel out into the rural areas which I do a lot on my job.
At my home, with 4g I get a bit better than you, but not near as good as some folks can who live in very heavily packed metro areas. Like Houston or New York City.
