Definitely, the best thing to do if you use any of these frameworks is to wait until this gets cleared up by Apple. I don't foresee that taking too long. However, there is another line of thought here, and that is why you wish to use frameworks in the first place (Now, I am not going to bash frameworks as I have used some before as well).
The way I look at it, if you are an Indie Developer and do iPhone apps as a hobby and want it to stay that way, then I can understand why you choose to stick with a framework. In that case, this was bad news for you.
However, if you are working with an apps company, or want to extend your skillset, or think iPhone/iPad dev can become more than a hobby for you later down the road, I strongly recommend you take up Objective-C.
I, myself, was using Appcelerator Titanium to develop iPhone apps in Javascript before the ToS. After it, I switched to the native tools, and it has probably only taken me a week to get used to the SDK and the syntax and style of Objective-C. If you have prior experience with MVC, you will catch on to it really quickly. The API is what takes time to learn, but I feel I am better off to get the features directly out of the horses' mouth as it were, rather than through an intermediate source.
