The latest phone loads that existed when Solution Testing 'started' are in the SWP. An example of where we got a newer phone load from 8.0.2 is the 7921/7925 1.3.4 since a new phone load was available to fix a problem. An example where we didn't have the upgraded phone load in time is the SPA500 7.4.6. Which one are you referring to?
But when we considered the drag and drop capability that works for SPA, we made a decision not to 'restart testing' with the new phone load, and do understand that an 'upgrade' to a SWP can in some cases 'downgrade' a phone load.
I am hoping we discussed this in the release notes? I did a review but don't remember now...
