Have you ever been playing around in one application, and get sent a SMS message? Of course you want to reply to that SMS right away, but you would have to get out of that app and go to the message app. Not anymore! With QuickReply you can now send SMS messages right from....Anywhere actually! This iPhone tweak is great for people who are big texters and they are in other apps. Its even good if your not, and you don't want to be bothers going app to app. The source for a free version of this paid app is from SinFull iPhone. (SinFull iPhone Repo: http://repo.sinfuliphone.com) Or you can be cool and buy it. :D For a Video review of QuickReply make sure to read the whole article.
P.S. I wonder if they will come out with a QuickReply for IM clients like Beejive. If there already is, leave a comment please, and i will update this post :)
