4 Really Good Reasons to Jailbreak Your iPhone

Installing OpenSSH Allows you to login to your iPhone on the command line.
You can do all sorts of things like
your iPhone as an internet router
ssh is a bit geeky, so you can AppleShare instead.
Browsing your WiFi will show the iPhone as plain as day.
It’s the next best thing to the “disk mode” that old iPods have.
video recording
Either live over the internet via Qik,
or locally using
or “VideoRecorder for iPhone”
playing old arcade games
There are now both an NES (non-super Nintendo) and Gameboy Advance emulators for the iPhone.
I wonder why
hasn’t been ported yet?

iPhone: NetShare success, and running AppleShare

On Saturday I successfully shared my iPhone’s 3G internet connection with two laptops we brought with us to Thorold.

It was a bit tricky, because the iPhone seemed to latch on to the WiFi connection provided by the peer-to-peer network created on the laptops.
The trick turned out to be running Safari on the iPhone, which would kick it into using the 3G network (since the peer-to-peer network had no route to the internet).

Once the iPhone was on the 3G network, I ran NetShare.
Both laptops set the iPhone’s IP address as their SOCKS proxy, and we were off to the races (although Firefox was a bit stubborn about it – I had to use Safari to browse).

So it’s good to know that should we ever need internet access in Thorold, we can use the iPhone.
We can probably also use it in Wasaga, but I suspect that we would only get EDGE networking there, which is 10x slower than 3G.

I should note that even if you don’t have the NetShare iPhone app, you can achieve the same thing (on a jailbroken iPhone)
using ssh.


I also found another major reason to jailbreak your iPhone: running AppleShare.
My iPhone now shows up under AppleShare over the WiFi network, which allows me to transfer files back and forth with ease.
(Sorry Mike!)

It’s pretty cool to bring up a network browser and see “Reid’s iPhone” in the list of available file servers. :-)

Qik on the (jailbroken) iPhone

So they seem to have worked out the kinks with the beta Qik client for the iPhone.
Actually, the kinks were in their website’s handling of iPhone-originated video.

In any case, you can go to qik.com/rae
and see my short masterpieces.
Plus, if I happen to be recording at that moment, you can watch it live!
Ooooh, ahhh.

I will embed the video I just took at work for your edification and amusement. :-)

Jailbreaking an iPhone

This is just a note about living with a jailbroken iPhone. I think I’ll update it over time.

Current jailbreak tool is PwnageTool_2.0.2.tbz,
which works with the first iPhone 2.0 update, 2.0.1.

If you find you can’t use WiFi after jailbreaking, try:

  1. removing your WiFi network and adding it back again
  2. use BossPrefs to “repair user dir permissions”

Interesting apps for jailbroken phones include:

manually installed; it was pulled from the App store
NES emulator
play tons of old games!
Quake 1
Lets you tweak lots of stuff, including jailbreak-specific things like “SSH Server” on/off

How to install a *.app file

cribbed from MacRumors forums.

Using an SFTP application (I use Cyberduck), drag the NetShare.app folder from the desktop into the iPhone’s /Applications folder.

Open a terminal window, and open an SSH session with the iPhone:

$ ssh root@

(replace the IP address above with your iPhone’s IP Wi-Fi address.) The default root login password is “alpine”.

Next, go to the NetShare.app folder:

# cd /Applications/NetShare.app

and change the access file mask of the main application file:

# chmod 755 NetShare

Reboot (or re-spring if you know how) your iPhone.

You’re done!

Fun, eh?

Finally, a good-enough HD camcorder: Canon iVis HG11/HG21

click for larger image

Canon is releasing two new camcorders that record in AVCHD at 24 Mbps, the maximum bitrate for AVCHD.
The main difference between them is that one uses 32 GB of flash storage, while the other uses 120 GB of hard drive storage.
Both support an external SDHC slot (and you *can* shoot video to SDHC using the hard-drive model) for both video and still pics, which are 1920×1440.

I’ve been waiting a long time for an affordable, decent-quality HD camera.
The old, tape-based (HDV) camcorders had excellent quality, but only 1440 horizontal resolution (1920 compressed to 1440 and then expanded back to 1920 for playback).
Tape is also very slow.
The more recent AVCHD cameras have lots of good features, but the basic video quality has always been lower than that of HDV.

This increase to the maximum bitrate allowed for in the AVCHD spec should finally allow it to apprach and maybe surpass HDV in terms of quality.
Note also that AVCHD can play directly in most Blu-ray players.
