I have a jailbroken iPhone 4 on iOS 5.1.1 and I just installed the onavo extend and onavo count app in the phone. As a part of setup of these programs it needs to install a profile on the phone. But when inside the app I click the button to install the profile, the app crashes. This is happening with both the onavo apps.
Now I also have an iPhone 4S, and I was able to install these two apps and profile as well and it worked fine. I can also see the profile installed under
Settings -> general -> profile

While in the iPhone 4 I don't even have anything by the name profile under settings -> general

What seems to the problem in the iPhone 4 that I am unable to install the profile ?

Just for the record, the 4S is also jailbroken and on ios 5.1.1
