Hi, I used MS excel documet to keep track of my monthly expenses and other financial transactions in my old HTC Windows Mobile. Now I am using iPhone 3GS and I am not able to edit/save my old excel documents. Is there any excel like application exists for iPhone 3GS? Basically what I need is, to add more fields(customizable) and enter the desscription and sum up the amount. This is the basic thing I will do it in excel. Any suggestions?
