Two months ago I bought an Alcatel X060 usb modem from Simyo. Unfortunately I haven't got any 3G network available so the usual speed in my village is 45 mbps. It's hilarious!!! But yesterday I tried it in the capital city and the results were pretty good. Here you can see the speed test. Its 1 Gb approximately, not bad at all to check mail in an unusual situation like this when you are not home.
There is just one thing. I still haven't been able to make the modem work with linux but it's just a matter of time.
