Hello folks, my first post here. I have a few concerns before updating to 2.1. 1) At this moment i have the "stock" OS which was on my phone when bought it, if i update to latest 2.1 available will my battery life improve ? Or at least, will remain the same ? 2) The phone is locked on Orange and it has few touches left by them, on the back cover it's Orange logo instead of Xperia and i have 2 type of menu/homescreen, the one from SE and one customized by Orange. The question is - after update, i will still have the Orange screen or i will be left only with SE's ? Does it matter that the phone is locked on Orange when updating through PC companion ? 3) There are phones that after update to 2.1 (from 1.6) they lose CPU speed (480 instead of 600 for ex) and so on. Is this happening @ X10 mini also ? Will it run smooth as now, or even smoother ? I dont want to update and find out that it's more laggy because i can't return to 1.6 with a "normal" procedure. Thanks in advance for your answers, have a great day !
