How to Unlock a Samsung Gravity for Free

1. Call 1-800-T-MOBILE, or 1-800-866-2453, and request the unlock code. Some companies do not readily give out the unlock codes so be persistent. There is no charge for this, but they may ask that your account is kept current or that you complete the terms of your service agreement. Contacting the service provider is the only way to guarantee the unlock code is correct.
2. Ensure there is no SIM card in your Gravity and turn it on.
3. Input '#7465625*638*CODE#' using your keypad. In place of 'CODE,' input the unlock code that was obtained in Step 1.
4. Wait for 'Network Lock Deactivated' to appear in display.

How to Stop Unwanted Calls Without Changing Your Cell Phone Number

1. Check to see if your cell phone has a 'Send Straight to Voice Mail' feature. Some newer phones have this built-in feature, which allows certain callers in your contact list (or address book) to be sent straight to voice mail. All cell phones send calls to voice mail when the device is turned off. This feature, however, lets you keep your phone on while designated callers go straight to voice mail -- without your phone ever ringing. That's right! Your phone never even rings when they call. (Pretty awesome, huh?) Check with your service provider to see if the feature is available -- if not, request it. The T-Mobile G1 Android (Google) phone does have it. We'll learn how to use the feature in Step 2. If your phone does not have this feature, skip to Step 3.
2. To use the 'Send Straight to Voice Mail' feature, go to your contacts list or address book. Select the contact you wish to send straight to voice mail. (If you don't have the caller's number put into your contacts list, you must first do so. Sometimes you'll have to wait until they call again, if you don't know the number -- or look through your call log to find the number. In any case, the caller's number must be entered in your contacts list.) After you select the contact, activate the 'Send Straight to Voice Mail' feature for that number. The T-Mobile G1 Android (Google) phone gives you the option to check a box for this -- you'll see a green check mark when it's selected. Now the contact will go straight to voice mail when they call you. You won't be bothered by the phone ringing when it's that caller. (Other callers will be able to ring your phone, as usual, if it's turned on.)
3. Now you're sending the unwanted callers straight to voice mail and they cannot ring your phone. Great! But what if your phone doesn't have this feature? And what if you don't want to listen to those voice mail messages? What if the unwanted caller is stressing you out with threatening rants ... or heavy breathing ... or whatever? Here's where you'll discover the beauty of YouMail. Go to www.youmail.com and set up a free account. YouMail is absolutely free, although you'll need to receive a text message for the activation code. Once your account is activated, you can set up a contacts list. After you've put the unwanted caller in your contacts list, click the ditchmail symbol (a red circle with the cross-out bar through it) to ditch the caller. Now that caller will not be able to leave you voice mail. No more messages from them! If you've completed Steps 2 and 3, you've achieved what I call the 'Double Ditch' -- the phone never rings when they call and they can never again leave a message (from that number). You've effectively banished the unwanted caller from your life! If you've only completed Step 3, you will still hear the phone ring but at least they will not be able to leave you a message.

3. Input the number you wish to send a message to, your own information if necessary, and any other required information. Select the appropriate carrier, then send your message. The phone number you typed in will receive your text message.

How to Make Free Phone Calls Using Your Computer

1. Setup a free Google Voice account, which forwards calls to home and cell phone numbers. First, select a Google Voice number, then set up routing to your home or cell phone. The final step requires a confirmation call to your phone number.
2. Setup a Sipgate account at Sipgate One. You'll have to enter your cell phone carrier and enter a text message confirmation code. The site then asks for contact information and a password. After the information processes, you'll get access to the Sipgate software download. Kevin Purdy of Lifehacker recommends that users simply download the software, but don't install it yet.
3. Confirm your address through the emailed confirmation. You'll then confirm your exact address and select an number with an appropriate area code. Select options for a free, single phone number.
4. Surf to Sipgate.com and sign into your Sipgate account to change your settings. In the 'Settings' section, select 'Phone.' Click the cell phone number supplied during setup and select 'Delete.' The new highlighted phone number will say 'Phone of [Your Name].'
5. Click into 'Voicemail, Forwarding and Hunting Rules.' Clear all rules so that the screen says that you've set no rules for your number or account.
6. Surf back over to Google Voice and click 'Add Another Phone.' Enter your Sipgate phone number, unchecking the text message option, then save.
7. Open another window and sign back into Sipgate. Run the Google Voice confirmation call. When the call comes into Sipgate, click the 'Dialpad' option to bring up the number pad. Type in the Google Voice confirmation code to verify the phone number.
8. Make phone calls through Google Voice, and receive phone calls through Sipgate. When Google Voice makes a call, select the contact name of your Sipgate number from the Google Voice dropdown list.
