Warning: IF IT DOES NOT WORK. DONT TRY MORE THAN 4 TIMES. IT CAN LOCK YOUR PHONE REQUIRING MAINTENANCE.
1. Turn off your phone, put in a SIM of a different provider.
2. At the wrong card message, type *#9998*3323#. A message will pop up telling you to press exit, so hit the right soft key. Choose number 7 (or 8 or 9 will work too, I think). Your phone will reboot and your SIM will work.
3. Type *0141# and then hit call. This will give you a message saying your phone is personalized.
4. Power down your phone and insert your SIM. Then power back up your phone.
5. At the SIM pass code prompt type 00000000, that is 8 zeroes. So that will totally UNLOCK your phone."
All you have to do it type in the unlock code
That will unlock the phone to use on any carrier; The problem you are faced with now is that the a707 only accepts 3G sim cards. If you are using T Mobile just ask them they should give you the code. If not, you are just out of luck as there are new firmware upgrades for the a707 at this time. GOOD LUCK. This is not illegal nor is it illegal for them to lock a phone
or you can unlock / unfreeze your phone by original USB cable
You need a sim from another carrier for this to work:
1) Insert Incorrect Sim
2) Enter *7465625*638*00000000*00000000# (wrong sim message again)
3) NEXT ENTER #7465625*638*00000000# (wrong sim message again)
4) NEXT ENTER *#7465625# (You should get the following lock status)
all locks are inactive...these are all the locks...
network lock - inactive (if this is ACTIVE, try the above code again)
subset lock - inactive
sp lock - inactive
cp lock - inactive
sim lock - inactive
activa lock - inactive
phone lock - inactive
auto network - inactive
auto subset lock - inactive
auto sp lock - inactive
auto cp lock - inactive
auto sim lock - inactive
Now the phone should be unlocked Permanently.
Hope this helps,

I don't think you easily can as the X4xx series appear built specific to provider; X495 is Tmobile, X496 is AT&T, and I believe X497 is Cingular.
