I just bought a new PAYG phone, so just popping in to add my experience! I chose to switch from Virgin to O2-not that I had a horrible experience with Virgin or anything, but the stars just weren't aligning for me to get a new phone with them.
Anyway, I was super impressed with the O2 website and my purchase experience instore- highly recommended! Not to mention they have an international "bolt-on" with their PAYG plans so that when you pay a one off charge of 4.99 you get calls to the USA for 5p/min!
And if anyone's looking to get a new mobile, I highly recommend the Sony Ericsson K750i! It was the hot new thing back in mid-2005 so the price has come down a lot from the stratosphere (I paid 80 quid for it.) And it has anything you'd ever want or need- triband so it works in the states, 2.0 megapixel camera, Bluetooth, FM radio, MP3 player, Memory Stick cards..the list goes on. I love it

(Can you tell I'm super excited about my new phone?
