1. First run of CarrierAppUtils ever
  a. Associated app with unspecified addedInSdk
  b. Associated app with specified addedInSdk
2. Firt run of CarrierAppUtils for a particular SDK
  a. Associated app with addedInSdk == current SDK
  b. Associated app with addedInSdk = current SDK - 1, and last
     evaluation SDK = current SDK - 2
  c. Associated app with unspecified addedInSdk
3. Subsequent run of CarrierAppUtils for a particular SDK
  a. Associated app with unspecified addedInSdk
  b. Associated app with specified addedInSdk
