Question about iPhone4s when using ChinaMobile Sim Card

Question

我是来自上海的用户。想必关于这个问题我不需要多问了吧？
我只想知道，苹果官方为什么到现在还没有公开此问题的原因及解决方案？
如果苹果通过固件升级来解决，那么希望苹果官方能给与我们消费者明确答复？
PS：
问题简单重复一下，这里不关任何国家销售的iPhone4s版本，据亲自测试均有以下问题：
1、在iOS 5.0的版本情况下，电话可以正常拨打，但是如果使用中国移动手机SIM卡，
     会不断不停的出现欢迎使用中国移动的界面，俗称“欢迎门”
2、在iOS 5.0.1的情况下，90%以上的时间，如果使用中国移动手机SIM卡，手机无法拨出
     接听任何电话，无法发送短消息，偶尔能收到短消息，以及无法对类似呼叫转移等做任何改变
所以，请苹果官方给与广大中国消费者一个明确答复及快速推出解决方案，如果继续这样下去，就算是
苹果粉丝的消费者也会失去信心！
I am from Shanghai's users. Presumably on this issue I do not need to ask, right?
I just want to know why Apple is still no official cause of this problem and open solutions?
If the Apple firmware upgrade to solve, you want Apple to give us consumers a clear official answer?
PS:
Problem in a simple repeat, not related to any country where sales iPhone4s versions have personally tested according to the following questions:
1, in iOS 5.0 version of the case, the phone can call normal, but if you use China mobile phone SIM card,
      Will continue to stop the Welcome to China Mobile's interface, commonly known as "welcome gate"
2, in the case of iOS 5.0.1, 90% of the time, if you use China mobile phone SIM cards, mobile phones can not make
      Receive any calls, unable to send a short message, and occasionally to receive short messages, and can not do anything like call forwarding and other  changes
So please, give Apple the official reply of the Chinese consumers a clear and rapid introduction of solutions, if continue like this, even
Apple fans will lose the confidence of consumers!

Answer 1

It is sad that Apple does not address this issue. The least it can do is find a way for the thousands of customers in China to downgrade iOS5.0.1 to iOS5.
The problem is with Apple's Head of China who did not report this problem as a red flag item.
Apple Genius was not even aware that there was an issue with China Mobile and iOS5.0.1
Apple is at risk of losing the millions of loyal fans.
