the LG Optimus uses a SIM card so if you transfer your SIM card to another phone from the same carrier It should work. your account it tied to your phone number not the phone itself.

Should be able to just touch the screen and slide up unless you have a password or a specific type of security in place.

Hi
You can unlock your HTC cell phone by calling your current service provider and ask for the unlock code. If you're not eligible for getting the unlock then you can buy an unlock code from an LG unlocking Service and receive the code immediately. It is not expensive, check this out.

I don't know how to change the time forward on my Samsung. The Serial Number is: 012629001921899.

The IMEI number is unique the each mobile/cell phone. The number is printed on the label under the battery. You can also get the IMEI number by entering this on your phone *#06# It will then display your IMEI number and you may also get a unique global serial number. Your IMEI number should be 15 digits.

contact your samsung mobile centre , they will remove it for free if your phone is in gaurantee perioud

No damage

How do I delete everything off of this cell?

If its the LG then copy all data in memory card and insert card in new phone
