Mundu - Mobile IM for Your Phone

Mundu Messenger is one of the most recommended software from me which I've already used it since Treo 650 (and also with my previous Motorola Q, Nokia E61, Treo 750v, O2 XDA Exec and now in Treo 680). I haven't use the Blackberry version and can't say much about it, but in my opinion this is far by the best instant messenger application for Palm OS. I prefer Slick for the Windows Mobile.

Anyway, I bought the license for only $11 directly via paypal and have no regrets. Just like their website listed, the good things from Mundu are :

• All-in-one Messenger
  View and chat with all your contacts across AIM®, Yahoo®, MSN®, Google® Talk, ICQ® and Jabber® within a single, easy-to-use interface.
  
• Conferencing
  Chat with multiple friends, colleagues or clients.
  
• File Transfer / Photo Sharing
  Transfer files from your mobile device to friends and colleagues.
  
• Smart Group Management
  Organize your contacts by services. Also organize contacts by groups & set alias for your buddies.
  
• Background Mode Support
  Stay connected on IM while you are on the phone or accessing other phone functions. Choose to be alerted by sound or pop-up when your contacts come online or when you receive an IM.
  
• Message Archiving and Chat History
  Save your important chat conversations and view them later.
  
• Manage your online presence
  Tell your friends when you are free to chat, busy, or bored!
  
• Scroll the conversation
  Have fun by scrolling the entire conversation - up or down - on your Android phone.
  
• Quick text messaging
  Copy & paste the messages received, send or receive emoticons , and very useful Quick text option to send commonly used messages like “Happy Birthday”.
  
• Direct Calling & Browsing
  Received a telephone number in chat?Click on the number directly to call. Similarly click on the received link and it will open immediately in the default browser.

Last thing is besides the Palm, Windows Mobile and Symbian, Mundu are now also available for Blackberry, Android, iPhone and maybe some Java Version (since there is a Sony Ericsson version in their site). You could download the trial version here and use it for 15 days. But trust me, the one-time-purchase is worth the price. ;)
