Yesterday I blogged about an Office Mobile upgrade and then had to remove the posting.  
This was because in the final preparation our Product team posted an internal site that was not intended for public consumption and it was then immediately removed.
A number of bloggers and Windows Mobile sites picked up on the post our web team made.
I've had a number of questions relating to what happened to the link and when the upgrade will be available.
Microsoft will put out upgrades for Office Mobile to support the new Office 2007 file formats in the near future.
In the next few weeks you will see more information pertaining to the availability of this upgrade.
