Not sure if this works with the 2008 but its something you can try, i put a sim card in my LX and was asking for a special code to unlock the phone, well right now tmobile isn't unlocking the sidekick, but you can trick the phone into using the sim card. First go to your settings, go to "SIM Center" and click on disable sim lock, enter in whatever your sim password is (if you dont know your sim password get your PUK (pin unblocking key) number which customer service will give you if you call 611, you can change that SIM pin by typing **05*PUKnumber*newpin*newpin#) now if you wanted to change it to "0123" if your puk was 9483992 its 7-9 digits you would type **05*9483992*0123*0123# now your sim pin is 0123. (trying not to make this super complicated) it will say sim pin not accepted click ok, now click change sim pin you can type the same sim pin 3 times if you want, 0123 0123 0123 now at the top of the screen bars will show up with a white phone beside it, go to Settings-Network Options-Scan and Select Manually, the SIM network should come up, click ok when it finds it and it will connect, now you can call and text on whatever sim you have in the phone

Need the free unlock code 357779035925815


For information on the SIM Unlock Code, refer to the following:
  • If you purchased a wireless phone from T-Mobile, your phone has been programmed with a SIM lock which will prevent the phone from operating with other compatible wireless telephone carrier's services. If you wish to use the phone with the service of another wireless telephone carrier, you must enter a numeric SIM Unlock Code to unlock the phone.
  • For customers with a T-Mobile Postpaid Plan, T-Mobile will provide the SIM Unlock Code upon request to eligible customers, provided the requesting customer has a minimum of 40 days of active service with T-Mobile.
  • For customers with a T-Mobile Prepaid Plan, T-Mobile will provide the SIM Unlock Code upon request to eligible customers, provided the requesting customer has a minimum of 60 days of active service with T-Mobile and either a Prepaid Plan account balance of at least $10.00 or a prior refill within the last 30 days.
  • T-Mobile will provide the SIM Unlock Code upon request to eligible former customers, provided that T-Mobile has such code or can obtain it from the manufacturer.

    You may request the SIM Unlock Code for your phone, together with instructions for entering the code, by calling T-Mobile customer care at 1-800-937-8997.

Securing your Shine
Secure your LG Shine and your account from thieves by locking your phone and your SIM card Losing a phone through accident or to a light-fingered thief is annoying, frustrating and potentially very costly, especially if the 'finder' uses your SIM card to make expensive calls. You can, however, lock both your phone and your SIM card with four-figure PIN numbers to prevent unauthorised use.
The first line of defence is to set a SIM card PIN. This means that whenever you turn on your handset you have to enter a PIN code before the SIM can be used. The default PIN code for your SIM is dependent upon your network; usually it will be found in a small booklet that came with the SIM card.
The PIN can be enabled, disabled or changed from the Security menu – but you only get three chances to enter it correctly. After those three, the SIM will get locked and can only be unlocked by entering the PUK (PIN Unlocking Key) which your network can give you. Enter the PUK incorrectly 10 times, and the SIM will be irrecoverably locked.
To activate a PIN code request, open the main menu by clicking on the scroll wheel. Click 9 to access the Settings menu and click 6 to enter the Security menu. The first item is PIN code request - click 1 or OK to open it. By default this will be set to off. To activate a PIN request, click 1; you'll now be prompted to enter the four-digit PIN. When you've done this, click OK, and if the pin was correct, you'll see the confirmation message 'Complete'.
To deactivate the PIN code request, you would simply select Off from the menu by pressing 2; you'll need to enter the PIN code whenever you change this setting.
PIN code request prevents another user from using your lost or stolen SIM card in their own phone. To lock your phone, and thus render it useless to a thief, you can activate Phone lock.
Two levels of handset locking are available. The first - called 'When power on' in the Phone lock menu - is to require an unlock code to be entered whenever the handset is switched on. This can be confusing and irritating when used together with the SIM PIN, so a second option is to only request the handset unlock code when the SIM card has been changed - called 'When SIM changed'. This means that if your phone is stolen, the thief can't use their own SIM card in it as the phone will need a PIN code to unlock.
To activate either option, go to the Security menu (clicking 9 for Settings and 6 for Security from the main menu) and click 2 to enter the Phone lock menu. Click 2 to activate When power on or 3 to activate When SIM changed. In either case you'll be prompted to enter the security code. By default this is 0000. Enter the code and click OK to confirm.
To change either code, go to the Security menu again (clicking 9 for Settings and 6 for Security from the main menu) and click 5 to enter the Change codes menu. To change the handset's security code, click 1 to select Security code, or to change the SIM PIN, click 2 to select PIN1 code. In either case you'll be prompted to enter the old code before entering the new code twice, clicking OK to confirm each time.

How to unlock special SIM code on Sidekick LX (T-Mobile) from USA


Hey. I own a Sidekick and I'm from the Philippines and you actually can use it anywhere, I figured.

Procedures:
1. Place the SIM Card and open the phone. A window will immediately appear demanding for your SIM PIN. Just press CANCEL.
2. Press Options/Menu or whatever the 3-horizontal bars on the upper left of your phone's called. Go to SETTINGS, then SIM CENTER.
3. Press Unlock SIM CARD
4. If you have a SIM PIN Code, type it. If not, just type 1234. then ENABLE. T he code won't be accepted. Press CANCEL.
5. Press CHANGE SIM PIN
6. In the Old SIM PIN, type your PIN. If you don't have one, just type 1234 again. Type 1234 for the other 2 questions.
7. SUBMIT
8. When "Waiting to register...." appears, all at once press OPTIONS, Letter L and that key on the lower right of your phone.
9. Exit
10. Go to settings again. then NETWORK OPTIONS
11. In the NETWORK SELECTION, press SCAN AND SELECT MANUALLY. Your phone will look for networks and when it's over, press DONE.

OK!
