Index inactive mobile site?

[RaksG]

Hi,

I have a question wrt Mobile version of a site.

Previously, we had a mobile site which is no longer active and there are possibilities of resurrecting it in future, so we have a 302 redirect which points to the homepage (desktop version).

Currently, the mobile site is indexed by the search engines.

To avoid the duplicate content issue, is it recommended to use robots.txt and block the spiders from mobile content or apply 301 redirect until the mobile site is up and running,  OR continue with the 302 redirect.

Any suggestions will be helpful.

Thanks,

I would make a very small mobile site (even if it is a single page) because there is thought that Google is liking mobile sites - particularly of local searches.
