SIM Unlock Codes

I have found that unlocking Samsung GSM handsets VOIDS THE WARRANTY of the phone. They are not supporting them on other networks either.

This is not true.

The SGH-S105 is a Samsung GSM phone. One way to unlock the phone is to contact T-Mobile. They will send you an unlock code. T-Mobile will replace your phone under warrantly even if your phone is unlocked.

Perhaps you're referring to the manufacturer warranty (if there is such a thing).

All the phones that I've owned that have needed repairs have been replaced by the carrier (Verizon, T-Mobile) and not the manufacturer. Obviously, one carrier won't support a phone if you're using it on another carriers network.
