Arghhhh I stupidly let my phone update last night so now I've lost HSPL and am running the 4.x bootloader... My plan when I get back to civilisation (currently in SA with a 3g dongle) is to flash one of the unlocked DFT Mango roms but now I'm going to have to revert back to my backup (lets hope that works) otherwise I'll get a brick.
In other news I still dont get all the hype around Mango, it's a bit better than NoDo but it's not revolutionary.
