If you’re like me and you check the new apps in Cydia on a daily basis, you probably saw a new app called Patchulous. The description of Patchulous may be interesting for anyone having issues with cracked .ipa files:

Patchulous patches .ipa files that have a second security measure such as TextGuru or BlueSkies. This can be used for other IPAs that may come out in the future with second security measures.

I googled Patchulous and came across this thread on MMI. Here is what user ButFuq (interesting screen name!) reports about Patchulous:

immediately after installing it to 3g iphone- all cracked apps not installed through cydia were erased. it was installed through cydia.

If I were you, I would not install this app until we know more about it.
