An excellent RIM KB for comparing the feature differences between BIS and BES:

Comparing BlackBerry Internet Service and BlackBerry Enterprise Server features

Kewl stuff! Thanks for sharing HockeyMod!

EDIT: Added it as "Comparing BIS & BES Features" in BlackBerryFAQ under the BlackBerry Information section.

Looks good, gunna make it much easier to explain to folks whats what!

An excellent find, Juwaack...thanks for posting this.

Nice, this will cut down on some questions...hopefully

Is there anywhere that has a good guide to which Blackberry plans on which carriers support BES? I.e., I'm looking at an environment where our users provide their own BB devices through their own carriers... and it would be useful to know exactly what they need to have on their carriers for BES support, and how much extra it costs. This information doesn't appear to be readily available anywhere.

hi. i recently just got the blackberry bold 9000 and its amazzinnnggg. i am in love with it. but this relationship is becoming so frustrating because I HAVE NO IDEA WHAT I'M DOING.

i joined a gprs monthly package just a few days back and i still don't understand why i cant use the blackberry messenger. all the service provider (China Mobile... im in shanghai, china) gave me was the IP address and the APN. and i don't even know if im a BES or BIS. or whatever it is. i dont even know how to set it up in the first place. i have a mac computer and i got the cd with the BB but then i can't even install it. does this have anything to why i cant use the blackberry messenger? i am COMPLETELY CLUELESS. can someone please please please please pleaseeee help me? it would save me and my bold's depleting relationship.

i am utterly and unforgivably confused.

please save me.

thank you good post that will help me when i get my blackberry!

Great post...wondering now how to increase the download size of a file on the BES...hoping this would have helped? Any Ideas

I hope one day Fido decides to offer BES on their plans.
