Well, my
K800i died at the start of November, to my disappointment.
From that, I went to a
Samsung B130 - screen the size of a postage stamp, horrible clicky buttons... basically the cheapest bit of plastic a tenner could buy me. After about a month of using it, I gave up - the microphone is so useless that it's quicker to walk to wherever the person on the other end is calling from and shout down their ear than try and get them to understand what I'm trying to say through the phone.
Today I ordered a new phone, and my first contract deal (through the power of the intarwebs, I've managed to get £8 a month knocked off, which translates into a saving of about £124. The contract in total is around £315, which I find amazing - to get the same perks on Pay As You Go would mean a £30 top-up each month, plus the cost of the phone: a whopping £745!). Again I'm with Orange (they're the only provider with whom I have signal at home and at Uni). The phone:
Sony Ericsson C902
Here's the old K800i:
I'm going to miss the joystick, but I'm incredibly happy that I've got the C902.

I've even been able to persuade my parents to pay for the first twelve months of the contract, and put a tenner towards the remaining six months. Silver tongue for the win!
