/*

* This module is for tone upgrading after the OTA, we will load it only when
|
|
* the system found it's a version upgraded.
|
|
*
|
|
* Please use the LazyLoader to load this, then simply call the perform() to
|
|
* execute the necessary migrations for the tones. There are two tone types
|
|
* we can upgrade, one is ringtone and the other one is alerttone, just pass
|
|
* them to the perform() and the upgrader will upgrade the tone type you want.
