Vorb Mobile can be accessed by any device with a HTML browser, including cellphones, PDAs and of course, your PC. Check it out here

Over the next few months Vorb Mobile will be developed so you can post and interact with Vorb on your mobile phone or PDA.
A list of mobile devices which should be able to access Vorb Mobile is at the bottom of this post.

P.S. Yes, I realize another NZ telco has been running a 3G network for a number of months, but until they understand that it's unacceptable to use irritating brats to advertise their services I'm going to ignore them.
