AppAdvice has teamed up with Shape Services in order to offer you a chance to win one of five  promo codes for IM+ Pro ($0.99) for iPhone, iPod touch, and iPad.

Keep in touch with friends, family, and coworkers with Shape Services’ IM+ Pro, an all-in-one social networking app.

With IM+ Pro you never have to worry about which of the many instant messaging services everyone else is using since it supports all major ones including Facebook, AIM, MSN, Skype, Yahoo!, and Google Talk. The app not only allows you to send text, but also allows you to send photos, videos, and voice notes. All of your chat history is stored on your iDevice as well as on the web, which you can access by signing into Shape’s web portal.

Where are you?

IM+ Pro includes a variety of other handy features too, like the ability to sign into multiple accounts, push notifications, personal status messages, a built-in web browser, and a variety of themes, backgrounds, sounds, and emoticons to choose from. The developer also recently introduced their own mobile-to-mobile in-app messenger, Beep, so you can get rid of your text messaging plan altogether as long as you have other IM+ Pro friends.

To have a chance at winning one of two IM+ Pro promo codes, simply hit that blue tweet button near the bottom of this page or retweet this post from your favorite Twitter app before 11:59 PM PST tonight (Jan. 5). We will then search the Twitterverse for all of the retweets and randomly choose our lucky winners. The winners will be notified via Twitter, so please be sure to follow us so we can send you your promo code via a direct message.

Non-Twitter users and those of you who want to increase your odds of winning can simply leave a relevant comment below before 11:59 PM PDT tonight to have a chance at winning one of the other three promo codes.

Feel free to participate in the giveaway via either or both methods. Only one entry per person per method is allowed, totaling up to two entries per person if using both.
