Just encrypt your device and pin lock it. This is the one aspect of the 4g upgrade I'm not comfortable with. Handing over a device to strangers with all my private and professional data makes me uneasy. Sorry, this rant is for another thread.I think the real question is once the bootloader is unlocked and system rooted, will unrooting and re-locking the bootloader be detected by motorola when sending it in for the 4glte upgrade???
