any way to trick an app to work on earlier firmware?

**Adrianna Gabriella j** · 03-12-2012, 05:00 PM

I've managed to get my iPhone from 4.3.5 back to 4.1 which was my only option.

all the apps i have are fine with it except one Accelastudy Portuguese, which soRAB law is one of my most important apps. it says it neeRAB 4.2.1.

is there any way of getting it to run on 4.1?

No. The short answer is, there is an API call needed from the 4.2.x or higher firmware. Without that API call, the app would crash.

there is a file you can edit that will make the apps and the device think you are on any firmware version you put but I did this for an app called celeste but later on i forgot and I tried to restore and I ended up with problems and there is no garante by doing this the app will work
