What are folks opinions as to the best way to back up my contacts on my phone. They are at present stored on the sim. I can export all those to the phone and thus have a "double up" of all contacts. I understand that I can back up via Kies - I do not have that on my PC. I understand that I can also back up via Gmail. However, that requires that I "give" my cellphone number to Google.
What other options are there for back up of contacts? Is it just as easy to write my contacts details down and file the paperwork in a place I know I can access readily. Or, am I just being paranoic? about possibility of loss of contacts/details?
