Problems after unlock... PLEASE PLEASE HELP

Hey Guy,

I just unlocked a 1.0.2 iphone. The Unlock went fine and after that I have started having problems. The problems are as follows:

1) MAIL
When I try to open Mail, the app just crashes and sends me back to the main screen. There are no settings for mail Settings Menu.

2) Contacts.
I cant copy over cantacts from itunes to iphone. It just says syncing for 2 seconds and then nothing.

3) YouTube.
Youtube is not working. I just kept getting the message "cant connect to youtube server" . I tried several hacks from the board but none worked. Also, I tried changing files in Lockdown and deleted the file in the activation folder as suggested by some on this forum. I also tried to download the youtube fix from installer.app.

Can someone Please Please help me.

Thanks,

DDMS

I think your unlocking has messed the permissions in your iPhone system.

You must set the MobileMail binary's permissions to 755. (search the forum for the procedure)

Search also for the last posted Youtube topic.

If i was you, i would try to restore and jailbreak again as after it doesn't need to unlock again, but just activate it.
