We have already known for a while what features are scheduled to come with BIS 4.1, and today RIM finally made it official. We posted word last week on the potential rollout dates for the update, and those dates ended up being bang on, with the exception of North America being one day later at Oct 11th. The full list of features, to refresh your memory:

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. For more information on performing a security wipe, please see KB28225.

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.

Pay close attemption to the section labelled “no interruption of email flow on SIM swap”, since the BlackBerry ID is tied to the device, not the SIM. This means that if you neglect to do a device wipe before you hand that device over to its proud new owner, someone else will still be getting those emails from your Mother nagging you about not calling. A security wipe has always been adviseable so you don’t accidentally ship someone a device loaded with your girlfriend’s contact info, but it’s even more important now that email service will continue.
