It's happens to everyone from time to time. Without meaning to, you accidentally lose a good friend's phone number. Many people find themselves in this situation when their cell phone dies suddenly, taking all the contact information with it. The replacement phone won't know your friends' phone numbers, and now you're left with a double whammy: not only can you not call them, but when they call you, you won't know it's them. Many people are reluctant to answer unknown calls, with good reason. Luckily, you can use reverse phone lookups and social networking sites like MySpace to make tracking down a friend's phone number easy and even enjoyable.

If you've had to replace your cell phone without getting a chance to backup the contact info, then the first step is to find your friends' phone numbers, and MySpace can be a great way to do so. Even if you don't yet use MySpace, chances are that some of your friends still do. By signing up and connecting with people you know, you can reconnect with friends you've lost touch with. In fact, some people even post their phone numbers on MySpace, which means you won't even have to suffer the embarrassment of asking an old friend for information you should already know. Once you've found a few friends on MySpace, chances are that those friends can help you find other contacts, making it easy to replace the information you lost at the death of your cell phone.

Once you've connected with contacts through MySpace, the next step is to use a reverse phone lookup to find out about the unknown calls on your replacement phone. After all, without your contact information, your phone can't display the names of your friends and family. Since cell phones make it unnecessary to memorize phone numbers, it's easy to think that someone you've known you're entire life is a total stranger. Luckily, by using a reverse phone lookup, you can find the name of any strange caller. This way, you can find out which of your friends have been calling you without talking to people you might not want to.

Reverse phone lookups are a great way to trace a phone number. In fact, you can use reverse phone lookups to find out about all kinds of unknown numbers, making it easy to find friends and protect your privacy at the same time.
