I could be wrong but I believe that app, available after jailbreaking, is called "Color Profiles".
Good luck.

The iPhone 4S, compared with iPad & iPod touch, has a yellow tint.
A yellow tint.
What kind of defect is this? Why is my screen yellow? And how do you fix it?
I think yellow is the "new" white & I don't think Apple is going to do anything about the screen temperatures of iOS devices.
I currently have an iPhone 4S with a very yellowish screen, but I've decided to just put up with it because I love the iPhone a lot. Part of the reasoning for coming to this conclusion is that I've been through 4 other iPhone 4S (from different stores, different time periods) & all of them have got various degrees of yellowish screens. Not one of those iPhones I came across has got a non-yellowish screen. This led me to humbly believe that based solely on my experiences, it may be fair to say that about 90% of the iPhone 4S have got yellow screens (of various degrees).
I could have kept going for replacement phones, but at some point in time, this exchange "madness" has got to stop as it is not getting me anywhere & the whole exchange processes are just a waste of my time, effort, & gas money. Maybe I'm just unlucky, but having used my yellow screen for quite a while, I do not see the "yellowish" on my screen anymore as I got used to it.
Note that I do still keep my iPhone 3GS which has got a cool blueish tint, so I can definitely see the differences in the screens when I compare both of them side by side.
