Is there a way to protect themselves from the iDevice Jailbreak?

Hello to all guys ... I am a developer and a user of the Jailbreak on the iDevice. Now I wonder if there is some trick to stop the hacking of our paid app store on other side, as Apptracks, Installous etc etc.

And 'possible to do all this? I ask because I've already been a user on my blog telling me how to download an app from installous does not work on your device jailbrekkato, as was shown a warning message that does not disappear anymore and that made ??it unusable 's app ... unfortunately I do not remember which app it would be helpful ..

We had a beta tester keep complaining that nothing we ever sent him would run. Just hang at start up. Learned he had jailbroken his ipad2. Sure enough, Titanium apps wouldn't run. Don't know the reason, don't know if it was just him.

You are wrong.

It's not beceause his device is jailbreaked that your application will not work.

Your application don't work, that's all.

And you have to know : some people have a jailbreaked iDevice AND buy their apps.

Ridiculous.
