I really newbie for iphone,
I always use my currect pda phone to be vt-100 terminal to connect to my company server to check and fix the system via telnet(I use mtoken from Choung Network).
But after I got this iphone, surely I don't want to carry both of my mobiles.

So could you please suggest if you know the software or any idea to let me try.

Thanks for your every idea.
I'm just a little Thai boy, please help.
