I found this great Android app ‘-= Save my Attach =-‘ on AppBrain: http://www.appbrain.com/app/com.mailtools.saveit

Those of us who use the Android G Mail app know that the inability to save attachments directly are one of the few pain points. This app or rather add on to the gmail application solves this problem ๐Ÿ™‚

If however you are lazy to do this and yet want this feature, there is always the new mobile website ๐Ÿ™‚
