T-Mobile has responded to allegations that the G2 will unroot itself if modified. Basically they’re saying tough cookies, bucko. Even if you’re a tech-savvy Android ninja, the G2 will never stay rooted. Until, of course, someone figures out how to wipe the ROM.
Code-Level Modifications to the G2
As pioneers in Android-powered mobile devices, T-Mobile and HTC strive to support innovation. The T-Mobile G2 is a powerful and highly customizable Android-powered smartphone, which customers can personalize and make their own, from the look of their home screen to adding their favorite applications and more.
The HTC software implementation on the G2 stores some components in read-only memory as a security measure to prevent key operating system software from becoming corrupted and rendering the device inoperable. There is a small subset of highly technical users who may want to modify and re-engineer their devices at the code level, known as “rooting,” but a side effect of HTC’s security measure is that these modifications are temporary and cannot be saved to permanent memory. As a result the original code is restored.
