IM+ All-In-One Messenger does more than just deliver mobile messaging, it allows users to send those messages using their mobile devices data plan rather than spending money on a per message basis.
One of my favorite features of the IM+ program is the ability to access multiple messaging programs from one single window. Essentially your friends lists will be combined into one easy to follow and even easier to access IM window. This is great for consolidating your messaging to a smaller display size, a precious commodity on a small handheld LCD display.
I also liked that I could set my status message and have the message display across multiple IM applications at the same time, with no need to individually set messages on each program. I use Yahoo, AIM and Google Talk and this is a nice convenience considering how much I tend to to change my status and messages as I head into meetings throughout the day.
The app also allows for full emoticon support. The collection of emoticons are pretty standard fare, but they serve a purpose and are easy to access via the device's controls and touch screen abilities.
The application also offers easy to pull up screen options, for instance, you can click on the "Active Chats" option to pull up a list of your current conversations which is a great time saver, while your buddies list can remain on the front of your screen when you're not messaging, this I found to be a great option when I just wanted to see who was online without having one or two conversations crowd up my screen.
