Ramparts have been breached - the end of 3's 'walled garden'

At LONG last, 3 opens up its network to non-3 authorised sites for its mobile users. The deal between Yahoo & 3 allows 3's customers to browse wherever they wish, not the totally restricted on-portal sites specified by 3. According to this CNET report, no launch date has been specified, but it's supposed be across 3's international operation. Pricing hasn't been determined either. Will this precipitate a GPRS / 3G per megabyte price war? Boy, I hope so, but I suspect that we might have to wait until early 2007 for that.....
