There are a few apps right off the top of my head I’d love to see available for iphone…
1) OpenSSH. I admin enough remote servers that if I had SSH of some form it would greatly increase the iPhone’s long-term utility
2) Some sort of Multichat aggregator client. Yahoo, MSN Messenger, AIM, etc..
3) xchat. It’s the only irc client I want 🙂
4) A 24 hour, daylight display world clock. The kind that costs 6000$ for an on-the-wall kind.
5) Thunderbird. It’s more forgiving.
6) Firefox. It remembers my fields.
That’s a good list for now.
