unlocking your phone will be only to use your phone with another carrier/operator, unlocking the bootloader its different, if your phone is or was locked to a carrier/operator/network branded you can NOT unlock the bootloader; operators request this to OEMs like Sony, and well there isn't a way around it, other than contacting your carrier/operator and requesting them to allow you to unlock the bootloader then they, your carrier, has to contact Sony so they can do that.

So, if i unlock the sim card, them i can unlock the bootloader?

[Uliwooly]

not at all, even if you unlocked your SIM or even flash your phone you won't be able to unlock your bootloader.

but why? i thought sony support that(http://unlockbootloader.sonymobile.com/&usg=ALkJrhhP-ssvMyb4jksvZ3J4-n18LBbGDg) because i want to root my phone, is there other way? to root it?

[Uliwooly]

I just told you why, it's not Sony it's your carrier/network who requested this to be disabled/not allowed.

You can do that only with UNLOCKED BOOTLOADER, i already try all the ways that i found

[Uliwooly]

keep checking the XDA forum, there might be a way around it, as there are alternatives for other Xperias.
