Screenshot utility for the iPhone

Yesterday, we had iPhone hackers making progress in
their goal of creating high quality tools for the
iPhone by developing a full-fledged iPhone application
with a graphic user interface and its own icon in the
iPhone home screen.

Today we have Erica Sudan from announcing
that she has created her own screenshot utility tool
for the iPhone.

The idea of the screenshot utility originated when she
stumbled upon an iPhone screen shot snippet that was
meant to be used inside the application. After
spending some time playing with the code, she got down
to writing the code for the screenshot utility taking
advantage of UIApplication's _dumpScreenContents:

The screenshot utility runs from the command line so
currently more for the technically inclined and
produces a PNG output of your screen

The other tip is if you set the iPhone to never sleep
and put it into camera mode, you can script it to take
screen shots every minute (or five minutes or however
long) to take time lapse series of images, however you
can take up to a maximum of 4 pictures per minute.

The iPhone application is available for free download,

to use the tool. As always please
remember to take the necessary precautions before
using the iPhone hack.

Stream audio from your iPhone to bluetooth headset

If you are one of those who was disappointed not to
see Bluetooth's A2DP profile in the iPhone feature
list then here is some good news for you as there is a

you should
be able to stream audio from your iPhone to a
Bluetooth headset.

What is A2DP?

In order to use Bluetooth, a device must be compatible
with certain Bluetooth profiles. A Bluetooth profile
is a standardized interface between Bluetooth devices.
Advanced Audio Distribution Profile (A2DP) is a
profile that defines how high quality audio (stereo or
mono) can be streamed from one device to another over
a Bluetooth connection - for example in this context,
music streamed from an iPhone to a wireless headset.

Now that we all know what A2DP stands for lets find
out how you can stream audio from your iPhone to a
Bluetooth headset. Audio here means audio from audio
tracks as well as videos.

So achieve this you need to do the following:
Pair a Bluetooth headset with your iPhone, switch on
your headset so that it can perform the handshake with
the iPhone.
Go into the Visual Voicemail screen and tap the Audio
button in the upper right (which is otherwise a
Speaker button when your headset isn't on and
communicating with your phone)
You'll receive an audio selection dialog much like the
in-call dialog box that allows you to choose where to
send the iPhone's audio.
Select the Headset option, then switch over to the
iPod and begin playing music or a video.

And you should be able to listen to the audio from the
headset, however the only not so nice part of this
iPhone tip is that the audio still plays from iPhone's

This essentially helps you remove the cable clutter
associated with a wired headset. So if you get this
working don't forget to thank Earle Davies the reader
at TUAW for the latest iPhone tip.

How to Reset the iPhone

If for some reason your iPhone freezes and stop
responding to any of your commands and you've tried
the button, switch or touch screen input but nothing
will make it respond.

You are left with no option but to reboot or reset the
iPhone. Here's how to do it:

To reset the iPhone, press and hold the Sleep/Wake
button and the Home button at the same time for at
least 10 seconds.
