I just lately obtained xperia x10 and had to just about right away upgrade towards the 2.1 system. I am detecting a small number of effects that I'm not picky regarding from the 1.6 version. However the obsession that is bugging me mainly is that I cannot connect contacts inside my phonebook to facebook and twitter accounts. During 1.6, when you modified a contact it provides you the preference to click LINK. It is not in new upgrade. Can somebody please assist me because as much as i discern, i ought to be capable to change and link each and every one of my contacts. That was the total reason of the xperia covering this timescape program.
