Best way to backup CONTACTS

I backup my contacts with Idrive Lite and Mobile Security.
Now when I restore my contacts, only the 1st email address for my contacts is restored, if I have 2 or 3 email address' for a friend, when I restore it, only the first one is restored and I lose the other 2.
Has anyone experienced this?
What is the absolute best way to backup contacts that way everything is backed up with them, that way when I install new OS I dont lose email addy's.

I use a Torch, and I installed .450.

Thanks

Best way to back up contacts is to save to your SIM card or use Mobile Backup if your carrier provides it.

Does SIM card hold everything? I.E. address? multiple email address, etc?
I thought SIM card backups can only hold the very basic....
