I did a speed test with the speedtest.net Android application last night. I tend to take results like this with a pinch of salt, but it seems that – even on full-blown HSDPA, I was roughly getting 512Kbps up and 512Kbps down. This compared to my 12Mbps home broadband.
Let me know how your network performs. Download the app, do a test whilst on HSDPA (not too many though, as it’ll impact your data allowance), then click on the results tab, hit the result you receive and then press “Menu” to email the result. Let us know, let’s see how each network performs.
