Backup contacts on phone

Question

Backup

Tell me the software for backing up a contact list for different OS

Answer 1

If the phone supports SyncML technology and you trust Google, then you can set up address book synchronization via www.google.ru/mobile/sync/ .
This solution is, for obvious reasons, platform independent and can be adapted to any OS.

Answer 2

On Windows Mobile, I use pimbackup , plus synchronization with Google, as mentioned above.

Answer 3

I used the OVI service on Symbian, it's very convenient.

Answer 4

opensync

Answer 5

In my opinion, there is a server option that should be supported by almost all modern phones - via SyncML.
I have not done this, and so far I cannot say anything about how convenient it is, etc.
But, this technology has a plus - it allows you to synchronize contacts with the server remotely, via GPRS, etc.
