I have the need to add some features of one of my SF application into a mobile device and been able to do the following:

1.- Connect wireless to the database (WiFi, WAN, Local wireless, etc.) and do some stuff (Don't know if I could use SF for this or would I need to go plain .Net)

2.- Capture customer signature electronically. I have not done this, but I guess would be a matter of access the signature hardware on the device via some library and save the signature image in a Blob field or something like that, again, would I be able to use use SF for this?



I have not started to search for Mobile Devices yet, so I would like to know if anybody here have done something like that and what kind of Mobile Device have you used?



The SF application handles an appliances repair shop, and the idea is to provide the technicians with the Mobile Device where they can see their routes and job specification, enter any new information about parts used at the customer and capture the customer's signature electronically in the Mobile Device. All communications with the database will be done online and live, I don't want to go with local data at the mobile device, probably I would need to build an ASP.Net application for the mobile device instead of using any custom library for the device.



I appreciate any comment, suggestions, experiences, etc. that anybody can provide here.



Thanks!
