There was a post stating that you could not use any form of Messaging (YIM, MSN,AOL,ICQ) on the Samsung Seek Phone. That is false. Not only can you, but it's all pretty much set up already for you...

Follow these steps.
Click the Home Button at bottom of your phone
Go to button says "Fun" at bottom of screen.Tap to select
Then Click the "IM" icon.
It will load a Java application screen,then it will ask you to open your Qwerty. then next step you will see available "IM" Applications. Touch the one that shows the "Yahoo Messenger" Icon and follow the instructions.
SO YES YOU CAN USE
YIM, AOL, MSN, AIM, ICQ. On your Boost Mobile Samsung Seek or any Samsung Seek Cell Phone!!
