@Arnab Thank you for your posting. I use Xperia mini running in Gingerbread 2.3.4 built number 4.0.2.A.0.84, I have some background data sync like Skype, Yahoo! Messenger, etc. They are important for me,so I don't want to sync off them. While for Facebook for Android, I sync Facebook Inside Xperia in order to can received notification or messages instantly. I don't have antivirus. My free RAM 131 MB and used RAM 166 MB.
