Please give me a convenient way to sync my contacts to my mobile.
Although there is a service of Plaxo Mobile Plus, it is available in limited area. Not in my country.
Sync with Nokia E-Series / Symbian S60 mobile
Contacts from E series to X6? Is that what you mean? Or are your contacts stored elsewhere?
For OTA - If you are having data like 3G, GPRS or even Wifi then there are two that I can recommend. I've been using both for a while now and both are good.
If its local like the PC then the Nokia Ovi Suite and Outlook work fine for me.
Also both are free!!!
