No, the function call exists on the OS, but only the OS vendor (or owner) can call it; you cannot have another app call it.
Put this into perspective tho...do you really want someone forcing s/w to YOUR phone?
No, I do not. And that's why I run Windows Mobile; you cannot push apps to or remotely remove apps from my phone (I do not have Enterprise OTA functionality installed).
And of course, if you buy an app for your iPhone and Apple then yanks that app, you lose it as well. Your apps will disappear if Apple yanks them from the App Store, much like Google with Android.
But the best part is that Apple screws the vendor by not refunding their commission on the sales. Yes, they will sell the app, take their 30%, and then when they yank the app they keep the 30% and you - Mr. Developer - have to refund the full amount. How's that for unethical behavior!
Once again, we have you reposting already REFUTED and proved wrong information. You were told this, with links, in a previous instance where you posted it. WHY do you post the same mis-information again?
That was posted over a year ago... and it had not been posted as a major issue again. Do you think that if it were Apple's policy to issue refunds and to charge back the full 100% to the developers there wouldn't be a bigger hullaballoo than just a few articles? Even in the discussion on that article developers chimed in to say that THEY were credited 70% when the sale was made... and debited 70% when a refund was made. REFUTING the allegations made by someone with an axe to grind.
Although the clause does say that Apple retains the right to keep the 30%, it also says Apple "may" issue the consumer the refund and that that keeping the 30% is linked to the reason the refund is issued:
"...a Licensed Application fails to conform to Your specifications or Your product warranty or the requirements of any applicable law, Apple may refund to the end-user the full amount of the price paid by the end-user for that Licensed Application. In the event that Apple refunds any such price to an end-user, You shall reimburse, or grant Apple a credit for, an amount equal to the price for that Licensed Application. Apple will have the right to retain its commission on the sale of that Licensed Application, notwithstanding the refund of the price to the end."
So far there are very few developers who have complained that Apple has retained the 30%... and many who have said they haven't.
