Download GoodReader for .99 cents and then you can open zip files in the app from your email. Used it over the weekend to open a zip folder from a website and it worked perfectly.
I have the goodreader and it is great i know it. However it seems that it cannot open the zip files in safari (that you access through html). Does anyone happen to have a solutionk for this?
I took it back. Goodreader can even open the zip files from safari (just copy the address into a new pagew and wait for download and then you will have the option). This is just an awesome application. Praises for the developers.
