A few days ago Josep sent me a link to a great knowledgebase article that details the differences between BES and BIS. This is a quick fact sheet and does not get down into the gritty details but it is a great resource for explaining the difference to new users.
Check it out at this link [...]

I have heard about this issue a few times today since BIS 2.5 went live with Windows Live push mail. So I thought it would be worth pointing out this Knowledgebase article that Remzi sent me.
Turns out that if you have Windows Live Messenger running on your computer it will not let your BlackBerry work [...]

While reading this knowledge base article on RIM’s site I ran into a bit of a snag. You can read what I mean below:
Important: HTML content cannot be created when forwarding, replying to, or composing a new email message.
So how long will it take for us to be able to send emails that are not [...]

RIM has provided some good guides on how to setup BIS 2.5 and what you can do with it. Remzi has done me a favor and emailed a few my way. Let me know if I missed any.
What is required to get BIS 2.5 to work – Essentially tells you that you need OS 4.5+ [...]

I know we have been mentioning BIS 2.5 quite a bit recently but its quite exciting. We finally have HTML emails for everybody on OS 4.5+. Nice work RIM!

As you must have heard from several reviews and posts,  BIS 2.5 brings HTML Emails, Native Attachment File Downloading and [...]

Raffy just sent me this message and it was confirmed by the same from Joe at www.dataoutages.com. It seems like the upcoming BIS 2.5 with HTML email and all will be going down next weekend. From what I can tell the activation will happen the next day.
From RIM’s announcement:
Maintenance Summary: BlackBerry Internet Service v2.4 upgrade [...]

If you are like me you will probably enjoy using IMAP for Gmail integration on your BlackBerry. I found that it has better syncronization of deleted and archived messages.
The problem is that the second you put in your email address and password into the BlackBerry Internet Service (BIS) form it automatically chooses to use POP3 [...]

At last ! Let’ hope this type of solution spreads for here. A Pre-Paid BlackBerry data package would open the device up to even more users. No more stuffing around trying to get your BlackBerry enabled for global roaming when you go overseas. (Not to mention any nasty surprise data roaming bills when you get [...]

All of you BIS users rejoice. BIS 2.5 is almost upon us and RIM has released the full feature list for the latest update. Many of these features requires OS 4.5 along with BIS 2.5 so don’t get your hopes up so fast… Thanks Josep for the tip!
In a nutshell:
