Yeah, I am aware of that, thanks.
Are there precedents of the GPE models w/unlocked bootloader?
Did anybody ever submitted a request to LG for the unlocked bootloader?
I know that HTC and even Sony will give the codes for unlocking bootloader upon request..
Carriers can and do play the "We have a telecomm network to protect!" trump card in the US.
It's not done overseas or (usually) with the GPE models - but - if it's unlockable at all, it always is on Sprint, and usually the same phone never is unlockable on Verizon.
For example, to unlock an HTC bootloader, you register at HTCdev.com and get your unlock token - no big deal. After that, not unlike unlocking and rooting a Nexus (for the most part).
But that same HTC on Verizon - you will not get your unlock token, reason=carrier restricted.
HTC capitulated due to a very public petition. We got what we asked for but were not careful. We get an unlocked bootloader with encrypted signature security still turned on - a big surprise because the stealth methods tended to do both at once. So - with an HTC, you have to flash kernels separately - or employ a stealth method to turn off encrypted security.
LG's phones in the US have been locked down so far as I know, with stealth methods that succeed to varying degrees. For a while with the G2, you could fool it long enough to install custom recovery (the tool you want to install roms and other root-related activities) and that was close enough for most uses.
All manufacturers update their bootloader in an effort to block out stealth methods.
Edit -
Oh and by the way - the Sony I didn't buy was because when you unlocked its bootloader with their help, you lost access to the Sony camera - the feature I wanted to see the most.
Outside of a Nexus, the HTC is still the most straightforward - unless you're on Verizon. And sometimes AT&T.
