I'm interested in doing an iPhone app for my day job as a pet project to learn iPhone app development. I'm curious how many companies are doing corporate iPhone apps (for internal use or for customer use). Does anyone have examples of how companies are doing iPhone apps?
One key integration I have seen is to centralize communications in one area. It is a powerful thing to be able to view all of your emails, phone messages, and text messages all in one place and in chronological order.
I'm currently doing in-house iPhone apps to assist workers in maintenance of complex mechanical systems. Fault notification, machine error logging, etc. Probably not a good project idea to get your feet wet, but it's one corporate use I know of.
iPhone and corporate use do not sound together.
What about doing it for Windows Mobile? It has a better image for corporate use and users could choose devices from many vendors.
Oracle has a bunch of Corporate(Enterprise) iPhone applications, check out Oracle Business Indicators or Oracle Business Approvals!
