I got onto an EPSRC funded PhD with 2(ii) and Masters (actually, two Masters) in the UK.
I would not worry too much about your degree grade if you are accepted. I'd say a practical aptitude and the knack of being able to spot detail that stand out in the data or physical specimens is more important, as is the ability to write in a succinct style that means any new findings stand out and are shown to be properly scrutinised with respect to existing knowledge in your field.
I had a tendency to freeze up in exams that did not help me during my first degree, however, good practical skills and ability to handle experimental work meant PhD was within my abilities, sucesfully concluded what seems quite a while ago.
Translated, if you really want to do a PhD go for it. An enthusiastic 2(ii) who is willing to give it a go is probably more likely to succeed than an unmotivated 1st at PhD.
