yeah this is the issue, ive used both international version and custom version of MM and had different results from one day to the next. I just updated now and i will try it for a few days, let it settle and if it is worse i will just downgrade as i was happy with LP 5.1 so i will let you know.are you using it? if so how it is, worth upgrading?
i used MM on International G4 and though battery was worse than on 5.1
