On older phones (Xperia x10) I was able to partition the sd card and have an ext-3 partition which is native to android/linux, link2sd was able to move system apps to it as it was already considered mounted at boot so nothing would unlink.. I have been trying to do this will the milo with little success, the phone considers either the internal sd or external sd card as 'damaged' when partitioned - I have tried a variety of tools which have been successful on other Sony mobiles, it then proceeds to reformat and partition the card(s) back to their default state.. Highly annoying, as by using an ext partition you could have gigabytes of system storage, so I can only assume there is something about the miro range which makes partitions unusable.
Performance is lessened when using ext partitions but that performance drop is significantly less than only have 50mb of ram available compared to 300 or 400mb!
If I have any success I will update you but at the moment im baffled..
