Well, after over a month and a half trying to get a refund for the faulty one, I've finally got a new one from a local Orange shop

. As far as my newbie phone eyes can tell me it's a OLED (05 build no. black is black in dark surroundings and not grey etc). Took a while to track one down though with all of the staff in every shop not knowing that there was a change in screen types. Very happy with it. If anyone in the North East wants to know where there is a couple left, just yell.
For cases I bought a HTC Desire S520, someone from the Modaco forums recommended it, very nice fit and secure, can post some pics if anyone's interested.
Think I'll give the customising a go tomorrow. It is Root > Clockwork Recovery > ROM in that order isn't it?
EDIT: Argh! Choice overload on memory cards. SanDisk 8GB Micro SDHC for £8.99 sound good?
