筆者也是業餘BlackBerry App Developer，剛剛收到來自blackberry world Team寄來的電郵，信裡面提到BlackBerry q5 將全面支援q10的App，不用作任何修改。而如果你的App本身已支援Q10的話，便會自動地幫你加至支援Q5，算是對開發者來說的好消息吧！
At BlackBerry Live 2013, we announced the upcoming availability of the new BlackBerry Q5 smartphone. Set to hit global carrier partners this summer, the BlackBerry Q5 gives the first taste of the BlackBerry 10 experience to those who want to have the best tools to explore, create and share.
We have great news for developers who have apps that currently support the blackberry q10. If your app supports the BlackBerry Q10, then it will also function on the BlackBerry Q5. No additional development work is required.
The BlackBerry Q5 is currently available in the BlackBerry World Vendor Portal for selection as a supported device. For your added convenience, if your app supported the BlackBerry Q10, we have automatically expanded your device support to include the BlackBerry Q5.
