I'm guessing that somewhere in your organization is the idea that CRM is not being used because it's not "portable" and it's a time drag on sales reps. If this is the case, then promise me. you'll question that general idea before you invest in mobile anything. I can almost guarantee that among the utilization issues is the notion that the system doesn't mirror the sales process.
Ok, jumping down off my soapbox, I wish I had some statistics, but I don't. I would check some vendor Web sites for case studies on mobility. I noticed a few good ones on the Salesforce.com Web site and I'm sure that anyone with a mobile solution (like Oracle or SAP) is also going to have case studies.
Caveat emptor: these case studies are obviously "tuned" to showcase the vendors' particular solutions and implementation.
