With "Unzip (from Mail and Safari)" you can open ZIP files out of the Mail or Safari application. The ZIP files will be unzipped automatically and you can browse, view and delete your files.
You can also export a file back to the Mail application (also as a draft).

REVIEWS: This App is working perfect unless you are open a valid ZIP File. Don't believe all the negative reviews.
If you have any problems, write to unzip@include7.ch.

IMPORTANT: To open a ZIP file out of the Mail application you have to touch the email attachment for more then 1 second. Quick view is not supported right now (detail view of the zip attachment).
If you see a blank screen, just click "back" and touch more then 1 second on the attachment.
