It's a security concern. The Android documentation doesn't provide a lot of elaboration, stating simply:
The procedure must be confirmed on-screen, and deletes the user data for privacy reasons.
However, the privacy concern is relatively straightforward to extrapolate. Once the bootloader is unlocked, the device can be flashed with unsigned images. ...

A permanently unlocked boot loader (BL) on a Nexus device is a big security risk.
It's only recommended for a pure developer phone.
An insecure BL enables all sorts of fastboot commands that can be used for e.g. doing the following:
Make a copy of the device
E.g. by booting a custom image (adb boot boot.img), then copying partition dumps
Erase data ...

Simply put, fastboot oem lock puts your bootloader into a mode that prevents you from overwriting your recovery image, without a subsequent fastboot oem unlock. This serves as a security precaution, primarily where the default recovery and firmware is installed.
Because:
The default recovery will only allow manufacturer/Google signed firmware to be ...

XDA has reported that the bootloader is unlocked, and custom kernels have successfully been flashed to the SGSII.

Both /data and /sdcard are erased when you do fastboot oem unlock. So you lose not just files on the "SD card", but all installed applications and their internal settings and data.
Yes, you can use adb backup to backup your data and then restore it later, either with adb restore or Titanium Backup Pro. However, when I did this (using adb restore), my MMS ...

No, the bootloader has no bearing on a SIM/network lock. The HTCdev site explicitly states this on the bootloader unlock page, in fact:
Please note that unlocking your bootloader does not mean that you will
be able to unlock the SIM lock. Unlocking your SIM lock is at the
discretion of your operator/carrier and is not part of the bootloader

No, they're completely unrelated things. As you say, an unlocked device means it's not locked to a particular carrier: you can insert a different SIM card to change to a different carrier, and it will work. A locked device will not connect to another carrier if you change the SIM card.
The bootloader is the first thing that runs when you turn the phone on: ...

No. Unlocking the bootloader will do nothing for Google Play. Even rooting won't do anything by itself as far as phone compatibility goes.
To get access to the apps without device restrictions, you must have a rooted phone. You then must edit the build.prop file to change your phone model to one that can install the app in question. See this android.se ...

Unlocking Your Xperia Play
Known issues
It is currently not possible to unlock the boot loader for CDMA phones.
Some customers with unlocked boot loaders have experienced problems when they are accepting over the air upgrades (FOTA - Firmware upgrade Over The Air). For customers that have unlocked the boot loader, please do not accept any over the air ...

Well, when HTC leaves it up to us, it's up to us, so I kept playing with it.
It turns out that the response I got is a generic response from fastboot: It does a piss-poor job of checking its arguments. That particular response, in effect, means, "invalid command arguments."
Yes, I made a typographical error and this was the result. It didn't occur to me ...

From this xda thread by albundy2010
I have seen quite of few people screw up their devices by not knowing what they are doing. So I am making this thread to simply tell people not familiar with fastboot what they should and should not do.
Fastboot oem unlock will unlock your bootloader and do a complete wipe of your device. As far as I know the only ...

I think your HBoot needs to be upgraded, and it sounds like perhaps you didn't run the RUU to do so. The HTCdev site notes that phones with an asterisk (*) next to them in the list must run an RUU before unlocking because the bootloader on the device did not originally ship with unlocking capabilities. So first you need to make sure your firmware is up to ...

Nexus Ones do not ship with 'S-OFF', they ship with a "locked" bootloader which then must be unlocked. You can actually use fastboot to unlock the bootloader, just run fastboot oem unlock on your PC using ADB (Android Device Bridge). MoDaCo has a post here with complete instructions and a multi-platform download of the needed tools.

Unlocking the bootloader will wipe your device.
You can however get root access without unlocking the boot loader.
If you then still want to unlock the bootloader, as you already have root access you can follow Sparx's advice and use a back up app before doing so.

If you're talking about sim unlock, it is possible to re-lock it back to the network as was often the case with old nokia dumb-phones. However, I have not seen this in practice with most phones now-a-days. Usually, once it is unlocked from the network, any sim card can go in place and use it.
However, if you're talking about locking the boot-loader - then ...

Yes I have a o2 xperia play and the only way for u to get cm9 is to unlock boot loader using omnius or any test point method as I didi this do not use sonys way as you will loose drm protected content and that is not what u want so use omnius then try and get into fastboot mode and it will work

The clue lies with the comment above But I just tried 'adb reboot bootloader', and it worked. which shows that adb is indeed recognizing the USB connection, but not in fast-boot mode which is where this answer comes in...
Sounds like the udev rule for the fast-boot is absent!
Do this: lsusb with the cable plugged in while the handset is in fast-boot mode.

The term "unlocked device" is as confusing as the term "ROM" (see the rom tags tag wiki). Only from the context one can tell whether it refers to "a device with an unlocked bootloader", or "a device without network/SIM lock".
This means, your question cannot be answered with a simple "Yes" or "No": though the terms are used as synonyms, "unlocked device" ...

Unlocking the bootloader will have no affect on the Play Store and what apps you have access to there. The main benefit of unlocking the bootloader is to be able to flash a new kernel and/or ROM to your phone.
In the past I have seen people post modified versions of the Play Store that have the country restrictions removed from the app itself. I am unable ...

It looks like your HBOOT needs to be upgraded to v1.02.0000 in order to use the HTCdev unlock method. The reason for this is that the Legend's bootloader did not originally ship with unlocking capabilities, so you need to upgrade to the version that added it.
Unfortunately, the HTCdev site will give you an RUU to run, but since it's an .exe file it won't do ...

I got this error, solved it thanks to this thread
http://androidforums.com/desire-s-all-things-root/444571-unlock-using-htcdev-com.html
Basically, this page http://www.htcdev.com/bootloader/ruu-downloads
is slightly misleading. If your device isn't listed, you might still need to update the RUU anyway.

Impossible to predict what their techs would do. Theoretically they certainly can deny repair service on bootloader-unlocked phones, since it clearly says that you are voiding your warranty when unlocking the device:
Important information
Please note that you may void the warranty of
your phone and/or any warranty from your operator if you unlock the

If fastboot from your computer can't find it, try following these steps exactly, beginning with installing the Requirements below. The most likely problem is some sort of driver missing, disallowing the computer from reading the phone in while it's in the bootloader.
This guide can be found on addictivetips.com, and uses a fastboot program from your ...
