The iphone runs UNIX natively underneath, so if you jailbreak it you get access to a full openssh install as well as a bash shell. There are also ssh terminal apps available from the Apple App store, though I have not used them so I cannot comment.
Rumors are that Android phones are coming out soon other than the G1 (which is T-Mobile only), so maybe some of them will show up on AT&T. They run Linux under the hood, though I have no experience with them to know if you can get ssh or a terminal.

I'm up for a cell phone contract renewal and am considering upgrading my handset. I looked at some devices at my local AT&T store but nothing really jumped out at me. I'm particularly interested in a cell phone that has a reliable ssh client, with ssh-agent and public key authentication abilities. Those of you who administer systems remotely, what mobile ssh client do you recommend? What phone would you recommend?
