小弟是新手
今天開啟手機裡的app store時發現有Youlu軟體要更新
就按了一下update之後，就要輸入apple id的密碼
輸入完之後，就出現信用卡的資料，要我打入授權碼
才能更新，小弟就不疑有他就輸入完授權碼後，就可以更新了！
1.請問這是正常現象嗎？因為這個軟體是免費的軟體！，之前有買過付費的軟體
2.聽我哥說，有收到apple寄來的信，代表有付到錢？？是真的嗎？謝謝！
3.免費版的軟體更新為啥還要輸入銀用卡的資料呢？
以下是蘋果寄來的信
Your Apple ID, xxxxxx@pchome.com.tw, was just used to purchase Youlu-Refined addressbook, Free messages, Awesome groups, Smart dialing from the App Store on a computer or device that had not previously been associated with that Apple ID.
If you made this purchase, you can disregard this email. This email was sent as a safeguard designed to protect you against unauthorised purchases.
If you did not make this purchase, we recommend that you go to iforgot.apple.com to change your password, then see Apple ID: Tips for protecting the security of your account for further assistance.

謝謝！小弟很困擾這個問題！！
