Talk about Nseries has published a “How to use the built-in IM client on your Symbian S60 device” You can find the guide here
“Mobjab seems to be much more stable than Packetbox ever was, and messages are sent and received with no delay at all. Contacts are also loaded quickly without any issues. I am really impressed by the speed of the service and I hope that it continues to be a success! I recommend you all trying out the Mobjab service if you like to use Instant Messaging, and tell us what you think!”
