Appcelerator Titanium: Yes
Appcelerator offers the Titanium+ program. There’s are three versions of this program and you need to chose either the small business or the enterprise versions. After reading complains from many users about high/excessive prices I tried to contact the publishers hoping I would be able to provide you with more detailed informations but Appcelerator never replied to my price request nor offers any infos on their site.
rhomobile: No
There’s no support whatsoever for In-App payments in rhomobile. If you need to use the toolkit your only option is to extend rhomobile with native code.
PhoneGap: Yes (No official)
There’s no official support for In-App payments at the moment and there are no plans for it. But there’s an external plugin for PhoneGap available that acts as an wrapper for Apple StoreKit:
https://github.com/phonegap/phonegap-plugins/tree/master/iPhone/InAppPurchaseManager
MoSync: No (but annouced for future version)
Official support for StoreKit is announced and even if it wasn’t, it’s always possible to extend MoSync with native functions.
WidgetPad: No
There’s no StoreKit integration of any kind available. There are no plans to create support for it.
Adobe Flash/Flash Builder: No
There’s no StoreKit integration of any kind available. There are no plans to create support for it. It’s not possible to add this functionality since the runtime environment is under full control of Adobe and can’t be extended.

Hi, I have a little correction – MoSync does have plans for supporting these functions on iOS and we’re also looking into various ways of providing something similar for the other platforms. Initial support is currently slated for fall 2011.
Of course, just like in the case of Rhomobile, it is already possible to do by extending MoSync with native code.
Don’t hesitate to contact me if you have any other thoughts or questions about MoSync

Thanks for correcting me. I couldn’t find any informations on integrating StoreKit into MoSync projects nor announcements thus came to the conculsion there’s no (planned) integration. Would you be so kind to point out where a developer can find informations about (future) StoreKit usage in MoSync?
