BIS 4.1
We heard back in March that we would soon see an update to BlackBerry Internet Service (BIS). As revealed back then, we will be seeing improvements to email including large email and native attachment support, inbox priming for new account integrations and additional language support. In addition to this, changes to the email flow on SIM swap means you'll want to be extra careful when switching devices, especially if you plan on selling your old BlackBerry. That's right, make sure you do a security wipe before passing it on. Who doesn't do that anyway? Seems like common sense to me. You can check out the full Overview from the BlackBerry Knowledge Base after the break.

For those of you wondering how you get the BIS 4.1 update, well, there is no way to get it, exactly. The update will be rolled out by RIM at some point and pushed to your device.

The BlackBerry Internet Service (BIS) is designed to provide BlackBerry smartphone users with access to email messaging, instant messaging, Internet browsing, and more. BlackBerry Internet Service subscribers can receive automatic delivery of email messages from up to ten email accounts on their BlackBerry smartphones.

The following is a list of new features being introduced with BlackBerry Internet Service 4.1:

Improved large email and native attachment support
Subscribers using BlackBerry smartphones with BlackBerry® 7 installed can:
  •     receive email messages that are up to 11MB in size
  •     download attachments in their original format that are up to 8MB in size
  •     view up to 300KB in an HTML email message
No interruption to email flow on SIM swap
Subscribers who insert a new SIM card in to their BlackBerry smartphone, including SIM cards from a different wireless service provider, no longer experience email flow interruptions. The BlackBerry Internet Service only stops sending email to a smartphone when the subscriber deletes all data from the smartphone, not when a new SIM card is inserted in to the smartphone.

Due to this change, before selling a smartphone, subscribers must delete all data from the smartphone (security wipe) to protect personal information, including email messages and synchronized contacts and calendar events. Note: This functionality will be available when BlackBerry Internet Service 4.1 is released in all regions.

Inbox priming for new account integrations
When a subscriber adds an email address to a smartphone, the inbox on the subscriber’s smartphone is pre-populated with up to 20 existing email messages from the email account.

Additional language support
Latvian and Lithuanian are supported by the BlackBerry Internet Service. Emails received in these languages can now be viewed on BlackBerry smartphones.
