Requirements unique to tablets:New UI: Multi-touch screen, virtual keyboard, new screen form facto
New Os: Android, WebOS, Customized Linux
Public API languages are different from ACM native code.Porting all ACM into tablet environment is not trivial.
No need for all features of ACM: Tablets already support nativeWi-Fi/Mobile connections, GPS, Phonebook, SMS
Best approach is to implement the 3 core features(Activation, Usage Meter, Wispr) on tablets:
Rely on native tablet UI, Public API, connection manager to ensure forward compatibility and easy maintenance.
Port the 3 modules from ACM native code to New OS native code
Provide Tablet OEM with device requirements to offer required pubensure correct implementation of these 3 features. Example: MSDINnumber, radio reboot
