I have this problem too.
I have read that if you have an app that supports the attachment type, then you can view / save attachments of that type using that app.
But can anyone point me to any good reference as to what attachment types different apps support? (e.g. GoodReader, ReaddleDocs, Documents To Go. The websites for these apps say they will read MS Office and PDF doc types, for example, but I haven't found a comprehensive list yet)
Is there an app that will save all attachment types?
My urgent need is to be able to read emails attached to other emails - attachments that show up as .eml files on the PC. Is there an app that will view / save an email message which arrives as an attachment to another message?
