V5 miltilanguage (all versions 3.3.1, 3.3.8 and 3.3.15) shows "Virgin" instead of "Orange" for Orange France.
Virgin in France is just a "low cost" carrier without a network of its own, operating on Orange network.
Carrier also displaying incorrectly for me after updating from 3.3.8 to 3.3.15.
"Amaysim" is displayed when 'Optus' should be displayed.
I have fixed it using MiuiSpnConf (thanks Acid).
If you guys want to correct it in the ROM, for Optus Australia, from Wikipedia, MCC is 505 & MNC is 02 (see below) 505 02 OptusSingtel Optus Proprietary Limited Operational GSM 900 / GSM 1800 / UMTS 900 / UMTS 2100
