Great!
I was running close to my limit this month on text so had to find a free text app. The only thing that was unclear which needs to be cleared up is that you CAN use your free Yahoo account to send and have your text push(ed) back to you. You just have to set the account up in your iPhone THEN make it your default mail account. Then on the Free SMS setup page just tic Use iPhone/iPod Email to ON. That was the only part that wasnt clear.
