I'd like to access files in an iPhone, such as using remotely connecting via ssh and telnet. But it appears that the iPhone's ssh or telnet are not supported. I can ping it, but cannot use telnet or ssh.
I read through some internet article, it appears that using jailbreak or Cydia it is doable, but I guess it would break my iPhone's license.
Is there an official way to ssh or telnet into my iPhone?
I loved ssh-ing before, but Airsharing is even better. You can upload files via a wifi connection to your ipod (using a browser or via webDAV). It was free for the first few weeks, but now it goes for $4.99. That's still not bad.
You can view office, image, pdf and html files.
(I'm not affiliated with airsharing, just a happy user :) )
You can't just access any file in a non-jailbroken iPhone.
You can access data files for your own programs during development using Xcode's Organizer, go to Devices -> your iphone -> Summary -> Applications -> your app, click on the triangle thingy to show the Application Data, which you can download.
Otherwise use something like Airsharing (see moogs' answer which came as I was writing this) to upload&download a bunch of files.
Even when not jailbroken, you can access some part of the filesystem with iPhone Broswer
