After jailbreak, iTunes issues

[frznd0g]

So i download tiny umbrella 4.1.9 back up my shsh. Then i download green poison jailbreak tool for osx. Everything went well with tiny umbrella and green poison, but now my iTunes on the mac and the app store on the iPhone 4 will not connect, it just hangs when anything i do asks for an user-name and password. It seems like the jailbreak/tiny umbrella screwed up how it communicates with apple's servers, because when i enter my correct user-name and password on iTunes on my computer it will just hang for like 3-5mins then provide an errors message every time. So please if anyone knows how to fix these issues I'd greatly appreciated. Also I've already restored my phone prior to jailbreaking, and this is a new mac mini im using so should be no issues there either (and yes it was able to connect before i starting jailbreaking) everything was fine.

So it seems the problem that was happening on my mac mini with iTunes was solved with a simple restart, but that's not the case with my iPhone it still wont connect, wont update apps or install new or already bought apps via the app store. I even restarted the iPhone.... nothing.

EDIT: i stand corrected the issue seems to be back on my mac mini, this is really weird how can it work after a restart then fail later. I'm really regretting that i even jailbroke my iPhone 4 in the first place... just one big headache
