i text and internets mainly.
its raaather fast.
i ran speedtest.net on my wildfire, and it came up as a 2mb connection!

you cant look at smut on their default browser, they just dont allow it, you cant even unlock it.
you have to go through the opera browser, which puts everything through a proxy by default, thus hiding the limited sites. (i only found this out by looking at thefixfixfix.com, not real smut! honest!)
you get a 14 day cooling off period apparently, whereby you can cancel our contract if your not happy.
(though i never tested it)
and if you move house, and have no coverage, APPARENTLY, they monitor your phone for 10 days, checking its location and reception, and will cancel your contract at any time if its not up to scratch (so the bloke in the shop said)
Phone in a crisp packet for 10 days if you want to get rid of it?
