Nexus S has been rooted, let the insanity commence! proclaims Engadget. This is only doable because Android's section is poop and it's exploited easily to acquire root priviledges [sic] adds a commenter.

Youll hit to defence me if I strongly disagree.

The Nexus S, like the Nexus One before it, is designed to allow enthusiasts to install bespoken operating systems. Allowing your possess boot ikon on a clean Nexus S is as ultimate as streaming fastboot oem unlock. It should be no surprise that modifying the operating system can give you root access to your phone. Hopefully thats meet the first of the changes you might make.

Legitimately gaining root access to your figure is a farther cry from most rooting exploits. Traditional rooting attacks are typically performed by exploiting an unpatched section hole on the device. Rooting is not a feature of a device; rather, it is the active utilization of a famous section hole.

Android has a strong section strategy, hardback by a solid implementation. By default, every Android applications are sandboxed from each other, helping to ensure that a vindictive or buggy application cannot interfere with another. All applications are required to tell the permissions they use, ensuring the individual is in control of the information they share. And yes, we aggressively fix famous section holes, including those that can be utilised for rooting. Our peers in the section community hit recognized our contribution to mobile security, and for that, we are extremely grateful.

Unfortunately, until carriers and manufacturers provide an easy method to legitimately unlock devices, there module be a uncolored tension between the rooting and section communities. We can only wish that carriers and manufacturers module recognize this, and not force users to opt between figure openness and security. Its doable to design unlocking techniques that protect the integrity of the mobile network, the rights of content providers, and the rights of application developers, patch at the same instance giving users choice. Users should obligation no less.
