I got a trueblue well i dont how long you've already been waiting, but no 3.55 CFW working eboots for Kmeaw etc have been released since may (except the sporadic duplex releases and uncharted 3) so i waited long enough got a TB a few months ago and its great you can play over 75 games you couldnt play otherwise with CFW. People complain it costs 60USD but thats the price of one game. Anyway i say its worth it because nothing else is doing the job currently.
Idk if the UK has any places to get it, but online mainly you have to order them from China which takes a few weeks or Canada. Lightake, yoyobase, modchipcentral (canada) are some of the more reliable places.
