Default [DISCUSSION] Google Play Nexus not wiping after Bootloader Unlock

So um...I'm kind of shocked.

I just unlocked the bootloader on my shiny new USA GSM Galaxy Nexus from Google Play and...my data was still there when I rebooted. No Android Wizard or anything.

It's as if I did nothing, but I checked MULTIPLE times and I'm unlocked. Got the unlock icon during boot and everything.

I may re-lock the bootloader now that I've rooted. I'm not sure if I will lose root, but I only rooted to run an adblocker anyway.

3) fastboot oem unlock
4) Flash an unsecure boot.img that has r/w permissions
5) Edit the right files to remove screen lock

But I still have a feeling that this behavior with USA GSM Nexi is intended. Probably because Google intended that phone to be sold only to developers who are likely going to be unlocking bootloaders anyway, and decided to simplify the process?

The USA version, as any other hspa+ version, DOES wipe userdata when unlocking the bootloader.

I have the USA version from the play store. My data wasn't wiped after unlocking the bootloader. Either way, its not a big deal. Warranty matters are much more important.

Nobody who has purchased a play store GN has reported wipe after unlock.

Mine from the play store did NOT wipe user data after unlocking. I am running CM9 and have locked and unlocked many times without wiping data.

Does NOT wipe actually. Maybe leave it to people with first hand experience to answer a question like this?

Although it may be a bug that will be fixed in a later update so I don't know if the failure to wipe is a permanent feature. However, I can verify my GN didn't wipe either after unlocking.

I have 3 Play store Galaxy Nexus. They all wiped data when I unlocked bootloader. I think that's first hand experience. If it doesn't wipe the data, then that's a security risk.

Example: Just yesterday, I got tired of using CM9 and fastbooted the stock images without -w. I didn't want to go into recovery to wipe data and factory reset (because that just wipes data partition, not usb storage), so while in fastboot, I did fastboot oem lock then fastboot oem unlock. If it didn't wipe data, then my usb storage should've had a clockwordmod folder, music that I precache, and other various folders that were created from apps that were installed, and I wouldn't be introduced to the welcome screen upon bootup. Like I said, if it doesn't wipe data for you guys, then that's a security risk and you should be contacting Google. Because if you lose your phone, someone can oem unlock your phone and go through your data.
