iPhone 3G user better don’t upgrade to iOS4 iPhone 3G用户还是别升级iOS4比较好

You have heard about iOS4, the latest iPhone OS for 3G/3Gs and iPhone 4. Including more than 100 new features like Multitasking, folders etc.

I hope im not too late to say this, after reading so many feedback from iPhone 3G user (is 3G not 3Gs!) from this Apple support forum , for your own good, if you are 3G user, i will advice you stay with your current 3.1.3 firmware, and don’t upgrade if those additional features are not what you needs.

Because you might end up with a jerky iphone after upgraded to iOS4. And you may have trouble to downgrade, since Apple stop signing 3.1.3 SHSH (something like a pass to connect to iTunes)

I’m not quite sure is this real or happen to all 3G user, but seems many of them have a same issue. Check out the video below:

你已听说iOS4，iPhone最新版的固件，适用于3G/3Gs和iPhone4。有超过100种新功能等。

我希望我不会太迟提供这消息，读了很多3G用户对升级iOS4后的回应和不满，如果你是3G用户，为了你好，我劝你还是别升级，继续使用3.1.3比较好。尤其是你对那些新功能并不在乎。

因为如果你升级3.1.3去iOS4，你的iPhone会变得很慢很迟钝。而你也很难再降级，因为苹果已停止为3.1.3的SHSH签证（一个类似链接iTunes服务器的准证）

我不能确定这消息准确与否，但看起来很多3G用户都有类似的问题。参考以下视讯：

May be is time to change to 3Gs or iPhone 4. Otherwise, just don’t upgrade.

也许是时候换3Gs或iPhone4了。不然，还是别升级吧。
