BlackBerry Internet Service is coming down the pike, due abroad on September 10th and in the US October 8th. As any BB aficionado would expect it brings a suite of improvements, bumping the maximum attachment size to eight megabytes, enhancing some security measures, and adding a delicious-sounding new feature called inbox priming. With this, the first 20 messages of a newly added account will be downloaded immediately, "instantly providing users with the reassurance that their email is setup and working." Suffering a bit of additional hypertension while waiting to see if those first few missives sync correctly? Your diuretic might just be inbound.
