Three's grandly titled The One Plan takes all limits and fair usage gotchas away and just lets you suckle bandwidth to your heart's content. And that explicitly includes tethering your phone to your laptop and using it as a 3G modem -- very classy. New and old customers will benefit from this, meaning that if you're already on this plan you're in line for a free upgrade. The offer's effective now and contracts start at £25 a month with a minimum term of one year. We'll be highly impressed if Three's network, never mind this deal, survives a full year of being bashed over the head by iPlayer streams and YouTube uploads, but here's hoping, eh?
