After jailbreaking my iphone to 4.3.5 I installed appsync 4+ via cydia.
after that itunes just won't recognize my device!
I need to delete it and boot tethered again to get itunes working with my iphone

anyone have an idea how to fix this?

We don't tolerate or support pirates here. We only help those who make a conscious decision to give respect for developers hard work by paying a fair price for their software.

If you want to continue piracy, then this is not the forum for you. I suggest you look elsewhere - there exist forums where other have the same low (or non existent) standards you have.
