Unlocking NAND Android H2

the instructions will come with the code, in an email from tmobile
all i did was

i put in a neighbors att sim card, power up the phone
window popped up ask for the code
put it in exactly as instructed, verify before pushing ok, b/c if u make x number of mistakes it will lock up the phone
after i put in code provided by tmobile, pushed the onscreen button - unlocked message appeared
power down, put in your sim restart good to go

it was very simple and easy to do, i did this with hd2 oem os sys -

 Thank you for taking the time to contact T-Mobile. Below you will see the Instructions for unlocking your HTC device.

1. Insert the foreign SIM card
2. Power on the device and the display should read "Please input unlock code"
3. Enter the unlock code and the device should display "Phone is unlocked."
4. Allow the phone to scan the network (or manually click on the antenna icon to do this)

It is very important that the instructions and SIM unlock code are entered correctly as listed. If you receive an error message while performing the instructions do not make any further attempts to unlock the handset. Please be aware that if an excessive amount of incorrect attempts are made, the phone will be permanently locked. You will need to verify the IMEI by pressing *#06# and contact Customer Care for support.


Thank You,
