To remove or move to your phone's SD card the unwanted Apps you never use and make extra space for Apps you really want. The N762 is cheap but as very little memory so rooting your phone is a nice way to optimize its space. (ie. I do not have a Facebook account or use Google+ on my phone removing those apps freed about 15Mb on my phone.)
To tether the 3G connection over a USB cable or through Wi-Fi. While there are some other options, rooting your phone will allow you to easily share your phone's Interweb connection with your other device.
To customize your phone. Some apps will allow you to customize just about everything on your phone but those require that you have a rooted phone.
Once rooted you will also be able to install ROMs to change/upgrade the version of Android currently on the phone and install apps allowing you to take screenshots or install a firewall to protect your phone.
The risks of rooting your Android phone
1. You can turn your smartphone into a brick. Well, not literally, but if you goof up the rooting process, meaning the code modifications, your phone software can get so damaged that your phone will basically be as useless as a brick.
2. Your phone warranty turns void. It’s legal to root your phone; however, if you do it, your device gets straight out of warranty. Say you root your phone and some time after that, you experience a phone malfunction – hardware or software related. Because of the Android rooting, the warranty is no longer valid, and the manufacturer will not cover the damages.
3. Malware can easily breach your mobile security. Gaining root access also entails circumventing the security restrictions put in place by the Android operating system. Which means worms, viruses, spyware and Trojans can infect the rooted Android software if it’s not protected by effective mobile antivirus for Android. There are several ways these types of malware get on your phone: drive-by downloads, malicious links, infected apps you download from not so reputable app stores. They take over your phone and make it act behind your back: forward your contact list to cybercrooks, sniff your e-mails, send text messages to premium numbers, racking up your phone, and collect personal data such as passwords, usernames, credit card details that you use while socializing, banking and shopping from your smartphone.And then read: Android Newbie’s Guide to Rooting and The Always Up-To-Date Guide to Rooting the Most Popular Android Phones.
