There are officially four carriers for the iPhone in the UK: O2, Orange, Tescos, and as of today, Vodafone. As with the other three carriers, tariffs start at 18 months long, the cheapest being £40/month, providing a free iPhone, 600 minutes and unlimited texting. The plan for 24 months is £35/month, though still more expensive when you do the math. Another 90 quid will get yu a 16GB iPhone 3GS, and £179 on the basic contract gets you the 32GB iPhone 3GS. You can see all the details spelled out at Vodafone\\\'s UK website.

A little competition never hurt anyone and in the case of Apple\'s iPhone, actually picked up sales quite a bit. On Tuesday, the iPhone stopped being exclusively offered by wireless carrier O2 in the UK. The device went on sale at 7 a.m. at Orange retailers with the carrier already claiming that the iPhone has gone over exceedingly well with consumers, despite already having been available to O2 customers since its initial launch.
