There has been some talk of what the best value method of getting the iPhone on O2 is, seeing as they now restrict you to one monthly rate for 9 months (to recoup the cost of the phone they're subsidising of course). I've created a couple of little tables to help people decide - it obviously depends on your usage needs of course. I want the 16Gb version, but I only really need the £35 per month/600 minutes option. I'm actually better off going in with the £45 per month and changing down to £35 after 9 months.... ok, not by much, but every little helps, to coin a phrase! 8 GB 16 GB Hope this helps!
