Not backing Motorola by any means, because I do want my droid x rooted as well.
But reasonable thinking tells me that Motorola Locks down the phones to keep users from trying to claim warranty repair/replacements caused by custom ROMs or Kernels frying the SoC due to extreme overclocking or other things.
I have no doubt in my mind that the processor in the Droid X could be clocked higher than 1ghz, but it's kept at 1ghz for the sake of battery life and longevity of the product.
It's similar to how some car manufacturers claim that modding anything in a car voids your warranty, but the truth to that is, the only warranty that is void is on the part that was modded, and not the whole car. Its a bit harder to prove to motorola that the cause of the fried SoC/Processor is not because you overclocked it too much but a manufacturer's defect.
I understand all points here, to simplify the matter, it'd be nice for motorola to say "Here, we'll unlock the bootloader on your phone, but if anything goes wrong with the phone, its not covered by warranty, and you're on your own."
I owned the Droid, and I had it OCed as well to 1.2Ghz, it ran fine with no issues except for reduced battery life....never did I hear of one user claim to have destroyed their phone due to OCing it, but the possibility is there, and that's enough to warrant motorola to lock the bootloader in my book.
Again, I'm all for root access and full control of the phone, but for people to say that it's not right for motorola to do so, I don't completely agree. If you have full access to the phone, you have a great potential to F U C K stuff up, and the first thing most will do is try to get warranty to cover it, when it wasn't a manufacturer's defect that caused it.
Flame me if you want, I'm sure I'll get shiet for this, just my .02 cents.
