Need rec for Excel editor for iPhone that plays well w DTTG

Greetings! I’m in need of a recommendation for a third-party app for iPhone iOS 4x that will play well with DTTG and allow me to edit Excel documents that are stored in DTTG 1.1. I would love two-way “Open-In” functionality. Does anyone have any suggestions/experience? Quickoffice? DocumentsToGo? All I need is a simple editor for .xlsx files (or even just .xls), I don’t want another app to sync separate files between iPhone and Mac–I have to do enough separate syncing as it is. Thanks!

I’m sorry to say that we don’t have any “official” suggestions, but hopefully someone from the community will have some suggestions for you.

Thanks, Jon.
