Picked up a new phone this week - a Sony ericcson k750i. Very funky little gadget, good phone and seems to have an infinite number of features. Certainly beats my old Nokia into the ground. Still not one hundred percent familiar with the new interface, but I haven't noticed any significant problems.
Was extremely worried yesterday - I took part in the Clare College Punt Race. We were sunk about halfway to Grantchester and I saw the bag my phone was in descend to the bottom of the Cam... Luckily the phone survived as I'd put inside two airtight freezer bags and then inside an allegedly waterproof bag. The waterproof bag was designed to shake off a bit of rain, being dunked inside the Cam did not help matters.
