這次除了文件管理，想到的基本都有了。

Also, when Steve was asked if there were plans to add Flash or java, his response was a flat: No.

The system actually runs the services apps need in the background -- the apps don't need to do them individually, so it's not a "true" multitasking system, but it seems plenty effective. There are seven services: background audio, which allows you to use the standard pop-over iPod controls, Voice over IP, which can receive calls in the background, location services for GPS and social networking (there's an indicator if any service is tracking you), updated push notifications with local notifications, task completion so you can finish things like uploads in the background, and fast app switching, which lets apps sleep and resume instantly. Notably missing? Anything for managing a conversation, like IM or Twitter, which is a big omission. Win some, lose some, we suppose

这个多任务只是伪多任务，并不是独立运行每个app，qq、msn之类的im app还是要靠push。

We just asked Steve and co. about the lack of anything that can keep track of a timeline for something like a Twitter or IM app. Scott says that the new save states for applications will be much better than the current situation. Steve also said that they stand behind push notifications and still think it's the right choice for this platform.

已经开始用4.0beta了，还不错，不过对于不支持多任务的程序来说，相当于“挂起”状态，对于支持多任务的程序，其实也就是放音乐那种后台播放。豆瓣电台倒是可以做做，QQ就不知道怎么做了。
目录功能相当实用，而且用 ...

Jobs的访谈那说了，im还是靠push。估计平时是所谓“Save State”的挂起状态,消息push来了，从Save State唤醒后再下载信息到本地。可以用BeejiveIM、IM+、Paringo这类有push功能的Im app试试。
