Do you mean that you can't access the Tersus application from your iPhone?
In that case, let's first make sure that you've created the <iPhone View>, and the application is accessible from the desktop browser using the automatically created URL in the format http://localhost:[port]/[appname] (as demonstrated in Demo Stage 1), as well as through the iPhone desktop preview, through the URL http://localhost:[port]/[appname]/iphone.html (as demonstrated in Demo Stage 2).
If all's well up till this point, then the URLfor accessing from the iPhone browser, is based on the one used in the desktop, replacing localhost with the actual ip address of the desktop, i.e. http://[ipadress]:[port]/[appname] (without iphone.html at the end).
Of-course, in order for this to work, your iPhone should be on the same network as the desktop (usually through wifi). You should also make sure there's no firewall blocking access to the specified port on the desktop.
If you're still having problems accessing (or if I've misunderstood the basic problem), please provide more details of the problem (error messages etc.). You're also welcome to export the application, and post it here.
For best results, use the Firefox browser..
