Auto AppTranslate is a modification with which you can translate all those applications that you have on your iPhone that are not in your native language, in our case Spanish.
We have done the test with the Instapaper application, which is only in English and the truth is that the result has been very good, in addition to uninstalling the application everything will return to normal.
You can download it by $ 2,99 on Cydia.
You will find it in the BigBoss repo.
You need to have done the jailbreak.
I do not get this application in the bigboss repo, or in the search, because it is
all the best
