CRM or Customer history & tracking

[msdker]

I'm looking for an app that will allow me to either add or access customer history. I want this to include:
Customer contact information
Appointment history
Customer Sales/purchase history including detail
Outstanding sales leads for each customer including when & what to follow up on
Reminders for follow-up in general when time has lapsed
Sorting by customer category
Sorting or mapping by area (if I catch myself in that area I can drop in to check in)

Right now I use a CRM program where I can set tasks to remind me to follow up on leads, but order history is too cumbersome so I have to print out the order history and keep it with me in a binder that I carry along. This has to be updated for 100+ clients a month. I can check our company's proprietary database for history through my iPHone but it is clumsy, locks up and hard to access easily.

I don't know how the mobile app is but we use Sales Force at work. May want to check that one out.
