Hi,
I did all the steps above but the YIM still gives message- Service not enabled for this handheld

I did the following:
-take backup of all settings
-download and install YIM for BB (removed precious install and restarted by removing battery)
-installed the 4.2 service book with YIM entry
-restart BB again
-login to YIM (it had my yahoo id and password still saved!, is it bcoz i also use yahoo Go!)

i checked the service books and it has entry (BBFS2[YHO])

COULD SOMEONE HELP ME!!! (i currently use a app called mig33 for yahoo messenger- but having YIM would be cool)
