I've got the Spreadsheet app and it works ok. I can import a spreadsheet via WIFI and alter it (in xml format), and then either export it via WIFI or I can email it in xml format. But what I can't do is receive a spreadsheet as an attachment and import it into the Spreadsheet app. Any ideas? If I do receive an emailed spreadsheet then if it's xls I can open it but cannot copy and paste from it into a newly created xml spreadsheet in Spreadsheet, if it's in xml format then I can't even view the attachment. Is anyone else managing to email in, amend, and then email out a spreadsheet in any format?
