An unusual but reportedly multi-sourced rumor has suggested that RIM might graft Android app compatibility on to its BlackBerry phones and the BlackBerry PlayBook. While officially planning to put a Java virtual machine on the PlayBook, it's believed by BGR to be "very much considering" Google's Dalvik engine from Android 2.2 and later as the basis. The trick could let it run at least some Android apps run and lure customers away who would otherwise have used a pure Android tablet.
