Just trying the 30 day trial and I have to say it works really well - with a 3G unlimited mobile/cell phone tariff this could be a killer application.

Just a shame I won't be able to sign up to this when I get my unlimited data plan in a month or two, as I'm in the UK!

$10/month is quite reasonable, but if Real launch this in the UK I bet it will be more like £10/month (which is ~$20 at the current exchange rate).
