Sorry, I'm not being clear. The idea is that you could take your phone and the CC outside right now and shoot it under a variety of conditions. Then you would use those shots of the CC to make new Camera Profiles in PS right now. One Camera Profile would be "PhoneSunny", for example. You save those in PS now.
Then later, if you take some phone pics outside WITHOUT your CC, you would load the pics in Photoshop and apply the pre-made "PhoneSunny" Camera Profile to those pics, even though you didn't have the CC with you at the time of your shooting. The saved Camera Profile would still make some corrections to your shots.
I understood that part. The phone photos that really need it are the ones you take indoors with poor lighting where you did not use the flash. They are the ones that really need the color checker. Generally the ones I shoot with my iPhone outside look pretty good.
