This is weird. UK carrier O2 has decided to do exactly what we've been asking mobile operators to do for donkeys' years -- it's going to allow users to chew through their data allowance in whatever fashion they like, without imposing artificial surcharges for tethering secondary devices to your phone. Up till now, you'd have had to swallow a salty £7.65 ($12.24) charge each month to get your tether on with O2, but for whatever reason, that has now been scrapped for subscribers on pay-monthly deals. Hit up the source link for a detailed list of O2's new contract options -- they don't include any unlimited 3G data plans, unfortunately, but we'll take what we can get for now
