Is there an application to edit basic MS Office documents?

I see the product can view attachments.   Is there a piece of software, even a paid option, to obtain an app that can both view and edit Word, Excel, and even PPT?

Boosted, it's you again.  Of course you were right about the Saints from the start. I must say that Drew Brees put on a QB clinic like never seen before at a Superbowl.  At one point, he was 29-32 and the three non-completions were: ball dropped by Colston that also went off his helmet (after that Colston was awesome), a spiked ball at end of 2nd half to stop the cclock, and another thrown away - else he might have been 29-29!
Not even Steve Young could move out of the poccket and release the ball as quickly as Brees, and he beat the master (Manning).

Thanks for your input.  I see Office Docs to go also peforms these tasks, and for a price but not too bad...$15.  For a full version for Balckberry it is $50 smacks.
