When Greg Hoffman opened his Christmas present from his mother，he was deeply impressed with the 18-point contract（合约）he had to sign，which says how he is to use his new iPhone．
“I just couldn’t understand．Why did mother really have to do this？”he told a reporter from Good morning America．
Some of the rules made by Janell．Hoffman are that she owns the phone and pays for it and she will always know the password（密码）and the phone should be handed over each night．Greg should also get ready to receive the calls from his parents at any time if he wants to keep his new phone．
“If it rings，answer it．Say hello and be polite．Do not ever pay no attention to a phone call if the screen reads‘Mom’or‘Dad’．Not ever．”Rule 3says．
Failing to follow the above rules and other rules such as not taking it to school and turning it off in public will result in the 12-year-old boy losing his new phone．
“You are a good boy and you should get his gift．But with acceptance of his present come rules．Please read through the following contract．I hope that you understand it is my job to bring you up a well-rounded，healthy young man who can keep up with the changes of technology and not be ruled by it．Failing to obey the following list will result in losing your iPhone，”the contract says．
“I love you and look forward to sharing several million text messages with you in the days to come．”the contract adds．
The rules are made to teach him to break the bad habits that many teens get into when using their mobile phone．
