Hi,
I recently had my site with WordPress.com. I purchased a domain name with WordPress.com and realized wordpress.com kind of sucks because you cant customize that much stuff. So I purchased web hosting with iPage, and used their one click install of WordPress 3.0.1. I imported my XML file for my old blog and was back in business or so I thought. I have owned my domain less than 60 days so I had to point my wordpress.com NS records to ipage NS records. My site works perfectly fine however when I try to manage my site at http://domain.com/wp-admin it keeps redirecting to http://domain.wordpress.com/wp-admin so I am not even going to the wordpress.org admin page rather I am still going to the wordpress.com admin page.
