Bobby Shea has written a great blog entry on using your iPhone to RDP (remote desktop) into servers and workstations on your network using VPN, an iPhone, and an expensive but well worth it iPhone application called PocketCloud by WYSE (about $30.00 unless you catch it on sale).
This is an incredible solution to accessing resources. Check it out.
Also posting a link to WYSE:
I was able to get this up and running in about 4 hours and you’d be amazed at the performance over AT&T’s 3G network. WYSE even has a video of their software in action, a must see if you’re in IT, and even more so if you’re mobile.
Oh, and did I mention that it has built-in support for VMware View? 🙂
