I was asking this also afew days ago...from what i was told importing contacts to google saves all the info online just incase your phone does a swipe and looses it. i still have my contacts saved to phone so i might have to save them to sd card and import them over. i guess google is safer, almost like a back up of all info etc...& if you add address, email etc then its worth it.

 

^^ yea what he said... im doing this as we speak...
