Hi,
several weeks ago I asked about the TOS of Apple and upgrading an existing app and someone told me that it is still possible to upload an app to itunes store but Unity team did/can not announce that officially!!! So I am really confuse; is it really true? Has anyone uploaded a new app to app store recently(I mean after new TOS)?
unity apps are uploaded on a daily base and about once per week somewhere on the globe a unity application is even featured 
Nothing to worry.
Also unity technologies is working on “Plan B” (see blog), which will allow to omit mono completely on the iphone target and instead work with the natively supported language and the sdk directly
