I forgot to ask, are you thinking about an app or a web app? If web app, you can go a long ways with an android device as well.

>Thank you for the input. I suppose I have no excuse any more not to start doing something for an iPhone. I think the first thing is to buy an iPhone <g>.

>>You can do a lot on an Iphone. The user may not be able to type as fast although, I have seen users experienced users text really fast. The main issue is you need to learn how phone apps work and don't try and change the rules. My first attempt was not accepted because it worked more like a normal web app then a phone app. Now my users like my application since I change to the App way. Doing invoices, CRM notes, call backs should not be a problem.

>>>I am in the process of writing a functional description of an add-on module (to my VFP application) for an iPhone or iPad. But when I start describing what I would like a user to be able to do, the iPhone screen seems to be too small. I can see how this functionality can be implemented on an iPad screen, but iPhone?! What do you think? What kind of business functionality can be done on an iPhone (or any mobile device for that matter)?
