RIM has announced its stance on jailbreaking BlackBerry products and declared that it will quickly squash any jailbreak methods that arise.
On hearing reports of a jailbreak for a BlackBerry product, the BBSIRT will quickly triage the underlying issue and method used to perform the jailbreak. If it falls into the first category, where extensive user interaction is required, we will seek to address it in a future software update. If it falls into the second category (where a vulnerability is exposed with little to no user interaction), that is an indication of a more serious underlying issue and will most likely result in the release of a security update to address it as soon as possible. When this happens, my team publishes a security advisory or notice. These notifications typically offer an assessment of the issue and the required steps customers should take to resolve the vulnerability.
To be clear, RIM recommends against installing any jailbreaking tool. Customers who use a jailbreaking tool on BlackBerry products void the manufacturer warranty and also increase the long-term risk of negatively impacting the stability and user experience of their BlackBerry products. Use of a jailbreaking tool could also amplify the impact and severity of a future security issue, making your personal data more vulnerable to theft and more difficult to protect. If new jailbreaks for BlackBerry products are reported, rest assured that we will evaluate them and take appropriate action to help protect customers.
As company that’s sinking, perhaps following Microsoft’s lead might be a better way to deal with jailbreaks.
