For BB10 you need a 114x114 application icon. Please note that there is a bug in the current apk2bar which resizes automatically the icon to 86x86. Therefore, your icon will look pixelated.

This is a feature that will be resolved in the 1.5 Gold SDK release. (Coming soon!) If an xhdpi 96x96 icon is present, that is what will be packed. This will scale correctly on PlayBook and BlackBerry 10. You can also include higher resolution icons and they will be scaled correctly.
