Re: API for integrating SD 4.5 with Blackberry phone device
SD's API is a object API allowing you to retrieve, create, modify and delte objects stored in ServiceDesk. It itself does not provide any GUI - you need to build some functionality on top of that. For exampe Service Pages are built using this API.
If you want to have some tailored interface available through BB you basically have 2 options:
1) Create a tailored application GUI application on top of SD'API
2) Create a WEB application using SD's API that will serve HTML pages that will be viewed on BB. For this have a look at Service Pages as a sample - it can be modified to suit your needs.
