Thank you all for the updates but nobody has been able to answer the question yet so let me clarify?

I know that Tmo list it on their website in addition to Blackberry listing it on theirs. However, they have this little "*" before the list of features implying not all features will work on the device without additional services.

So more specifially my question is will the IM work without the BES since it is not using OS 4.0 or will it require it.

Thanks
