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.
