A Status Update on Unlocking and Unfreeze Codes

Just wanted to let everyone know where I am in terms of unlocking and unfreezing the Behold.

The services I have tried are:
SRS Client
Kulankendi Client

SRS Client lists the Behold in it's documentation as being supported, but I'm having problems getting the computer to correctly recognise the QXDM drivers that enable the phone to be unlocked.

Kulankendi doesn't support the Behold, just the Tocco, so that was disappointing.

In terms of unfreeze codes, I'm going to experiment by calling T-Mobile and Samsung to see if they can provide me with one.
Through research, I've found that the unfreeze codes are unique to each phone; there's not a set unfreeze code.
To enter the unfreeze code once your Behold is frozen:

1. Remove T-Mobile SIM chip. Insert unsupported (ATT etc.) SIM chip.

2. Turn on phone. An error message will appear about the phone being frozen and offering two options:
SMS and Keypad.

3. Click Keypad. Enter unfreeze code. Cross fingers, toes, legs, arms, genitalia etc.

Haha crosss everything =]

the unfreeze codes, lets the handset be used with other carriers sims.  There is a program that will generate this code by the individual IMEI number.  Most companies leak the program,  Samsung keeps theirs secret so you have to call to get your unlock number from them or the company you purchased the handset from.

But you can call them for the unlock code they will email it to you.

Yes free of charge.
