Using fMMS on 3 UK network

Ok, for some reason I have now got this working.

Anyway, the correct setting for MMSC is

http://mms.um.three.co.uk:10021/mmsc

I have changed it in the Wiki.

Filling in and then greying out the "use proxy" fields in the "3" APN seems to work fine; you don't need to make a new "3 MMS" APN.

(Using version fMMS 0.3.6)
