well ok I just removed customize cause it wouldn't start reinstalled and now it asks to create an account. I already signed up via website last week so if create an account says my email is already taken, where is the option to login with an excisting account
This repository now has a Customize 2.0 Fix for easy installation through Installer.app. It should fix all of your Customize crashing problems: http://planet-iphones.com/repository
You may need to refresh winscp. Also if you don't have symlinks it will be in /private/var/mobile/Library
go to installer and search for something like suid fix. install it and customize should be fixed. i had the same problem but now its fine
