Hello all,
Yesterday, I discovered that the Gmail app refuses to open or save attached zips (or other archives) because they "could contain malicious software." Well I don't appreciate Google making that determination for me, so I modified the latest Gmail.apk to remove the restriction and thought I'd share. This is based off Gmail 4.2.1 and should work on most devices.
This will allow you to download attachments that were previously disallowed by the Gmail application. You will need another app that is capable of opening a zip/tar/etc file installed.
Disclaimer: I am not responsible for whatever happens as a result of using this modified version. If it goes crazy and emails embarrassing photos to all of your contacts it is neither my nor Google's fault.
That said, the changes are pretty minor and so far seem to work as expected.

These instructions are only necessary if you wish to modify the APK yourself, otherwise see above.

with
Rebuild Gmail.apk:
Sign and install!
*This seemed like the correct place to post since the modification applies to any device, but I apologize if this post belongs in another forum*
