Hi, You can unlock your My touch 4g using unlock codes!! Free unlocking services may not always be safe, so it is better to choose a reliable paid unlocking service!!! Unlocking using codes is easy and also safe!! You can get the codes from your service provider or from reliable online sites!!! I would suggest http://www.prounlocking.com/ , here they provide accurate codes at reasonable price!!!
One can unlock their T-Moble MyTouch 4g for free by contacting their local T-Mobile dealer or by calling the 1-800 number to their local customer support agent. These people can help them unlock any active T-Mobile Mytouch phone.
