Can no longer use & in app title to create &

used to be able to use the following to create an & in the app title
iOS
<name>one&two</name>

android
<name>one&amp;two</name>

Now using either combination on android or blackberry causes the application to say it is installed but does not appear on the device or launch from the studio

[INFO] : Installing apk: /Users/Martin/Documents/Titanium_Studio_Workspace/OneandTwo/build/android/bin/One&Two.apk
[INFO] : Installing app on device: GT-I8190
[INFO] : App successfully installed
[INFO] : Starting app: com.anvilgroup.globetracker/.OneTwoActivity

Works correctly on iOS but not android or blackberry, replacing & with and builds and runs correctly on android and blackberry
