Is there an iPhone application same like MS Office Suite? I am wondering if there is any iPhone application same like MS Office suite, I mean Spreadsheet, Word Processor and so on. 

If you know a free app it will be better if not so what is the best pro payed one
Not exactly MS Office but Apple has just released Numbers (SpreadSheet), Pages (Word Processor) and Keynote (Presentations) for iPhone. 

Each of them is priced $9.99
