Is there a way to reply texts from your PC?

I know I can do it with Kies Air, but is there another way to do it?

Check out AirDroid, it's a pretty slick app that can do that.

AirDroid does it also.. airdroid.com

You can also use your email, every carrier has their own, I believe AT&T is :
1234567890@txt.att.net
The numbers represent the phone number of the recipient.

Airdroid is AWESOME!
Thanks for the suggestion!

Or sign up for Google voice. That works too. Lol
