i want to unlock my phone so it will be sim-free,withot purchasing unlock code,is it possible?
if i unlock my bootloader it will help?
there are other possible ways ?
I believe, network unlocking will only work with an unlock code. So you have to buy one.
Unlocking the bootloader wont help in this situation.
Anyway, if you have a Droid, then your bootloader is not locked by default, but if you have a Milestone, theres a bad news, you cant unlock its bootloader.

Anyone find a way to unlock the bootloader on the i537?
Can I remove my sim while waiting for the bootloader unlock period to use it in another phone?
Yes you can.
Just got this phone and I've been able to click the oem unlock without unlocking the sim. Not sure if this is different than other t-mobile devices but I'd appreciate some feedback on if other t-mobile users don't need to sim unlock before unlocking the bootloader
