Hi, Yesterday my unbranded Galaxy S2 displayed that there is a software update available. I believe this to be Ice-Cream Sandwich. I believe it has downloaded and now the phone is waiting for me to accept the update/install. What I want to know is whether this update will reset all my icon positions in my "home" screen etc? Will it keep my bookmarks? My contacts are all sync'd (Google) as are my calendar reminders etc. I presume I won't lose those? How about my memos? Will I lose any of those I have stored? Sorry to have so many questions. Thank you for any help you may be able to give.
