To find out the LCD model (and manufacturer) of the display in your Macbook or Macbook pro, open a terminal window and paste the following code followed by enter:

ioreg -lw0 | grep IODisplayEDID | sed "/[^<]*</s///" | xxd -p -r | strings -6

This gives you e.g. the following information:
B133EW01 V0
Color LCD

The first line is the LCD model number, the second is the active color profile.
If you google the LCD Model number, you can find out more about your screen (contrast ratio, brightness).

For my screen (build into a 1st generation Macbook build in 8/2006) I get the following information:
Info about B133EW01 Screen Model

The screen quality of the new aluminium Macbook is not very good (compared to the Macbook Air and Macbook Pro) and prevents me from buying a Macbook at the moment. As the Macbook Air is not powerful enough for me and the Macbook Pro is too large (I travel a lot) I send the following E-Mail to Steve Jobs:

Hi Steve,

I am a longtime mac user and developer and considering to the buy the new macbook as a replacement for my old machine.
Seeing the macbook screen in a store next to a MBP and MBA however did not convince me quality wise (bad viewing angle, much more washed out colors than MBP and MBA).

These pictures I found on the net demonstrate the issue quite well:
Some might argue I could just get a MBA or MBP; but I am a heavy traveller. So the MBP is too large for me and the MBA is too limited (I need 4GB RAM). I do understand from a business perspective that the MB has an inferior screen as it's the entry line, but I would suggest to do one of these two options to attract even more people to the MB:

1) Put the better screen (the one the MBA currently has) into the 1499$ model and charge maybe 50$ more for it.
2) Make the better screen a BTO option for both MB models and charge for it.

Considering the buzz on the net about macbook screen quality I think these options would make a lot of people happy, who want a small powerful machine.



The just released 2.0.2 firmware update seems to improve the 3G reception for iphone 3G owners.

But what does it bring to the iPhone 2G?

Some things I found out so far:

  • It seems to be a bit more snappy (lag in typing and adressbook scrolling is less)
  • The build-number is 5C1
  • The baseband does not seem to be upgraded (still 04.05.04_G). That means everyone who pwned their phone and updates to 2.0.2 will loose the jailbreak, but the phone should stay unlocked and activated.
Some things that are still not fixed:
  • Backups still take way too long. If you just backuped your phone before the upgrade, backup seems faster initially but for me backup speed decreased as soon as I removed/installed some applications.
  • Installing applications takes still way too long if you have a certain number of applications already installed.

While you could already disable backups completly using DisableBackup 1.0 (or the some terminal commands) and iTunes 7.7, the updated iTunes 7.7.1 includes more  hidden options to configure the behavior of the iTunes Backup proccess. With iTunes 7.7.1 a hidden option was introduced to disable only automatic backups. Using the context menu for your device (as shown in the screenshot) manual backups can still be forced at any time. This is for sure a better option than the “disable backups completly option” available in Tunes 7.7. My small helper app DisableBackup has been updated to use this new 7.7.1 feature. You can download version 2.0 of DisableBackup here.

Disabling the slow iTunes Backup on Windows is a little more tricky, but it works. First of all close ITunes and then follow these steps:

  1. Locate your iTunesPrefs.xml file. It’s usually located in C:\Documents and Settings\username\Application Data\Apple Computer\iTunes or C:\Documents and Settings\username\Local Settings\Application Data\Apple Computer\iTunes.

    Hint: If the folder Application Data does not show up, make sure that hidden files are visible in the Windows Explorer

  2. Backup your iTunesPrefs.xml file
  3. Open iTunesPrefs.xml using a capable text-editor (e.g. Notepad++, Ultraedit, but not MS Notepad)
  4. Search for a section called User Preferences and paste the following snipped into the User Preferences Section after the first <dict>:


    After you've done that it should exactly look like the screenshot on the left.

  5. Save the file and restart iTunes. Backups should now be disabled. To enable backups again delete the XML Snippet from iTunesPrefs.xml file.

For those of you not familiar with the terminal I wrote a simple application, that lets you disable and enable backups for the iPhone/ipod touch with a single mouse click.

Download DisableBackup

Requirements: Mac OS X 10.4 or higher


This only works on the mac. Windows Users click here.

If you have installed a lot of applications on your iPhone, the backup can take forever. Itunes does not back the application data only, but the whole application binary everytime. To disable the slow back up type

defaults write DeviceBackupsDisabled -bool true

in the terminal. If you want to enable it again type:
defaults write DeviceBackupsDisabled -bool false
Note: This also disables backing up your SMS-messages etc. So you may want to enable the backup from time to time.

The MobileMe WebInterface does only support modern browsers like Internet-Explorer 7 or higher, Safari 3 or higher and Firefox 2 or higher. If you are still using Internet Explorer 6 (and many have to e.g. at their workplace) you are doomded: There is no way to access your email using an offical web-client from Apple.


But there is a solution:

  1. Open the webpage
  2. Login using your MobileMe-username (e.g. and using your password.
  3. You should have access to your mails and you can also compose new emails.

A lot of people using jaibroken iPhones/ipod touches have got installed OpenSSH. Some earlier jailbreak methods installed it even by default. While the Pwnage-method used to jailbreak the iPhone 2.0 Software does not install OpenSSH automatically, many users still have installed it manually to solve their mail or other problems using the the terminal. There is some serious issue with having OpenSSH installed (and running) on iPhone:
As the default password for the root user is well known, everyone can in principle access your phone. Imagine your are at a Cafe with an open Wifi. Everyone with some knowledge can log into your phone, copy all the data from it (SMS, Mails, Adressbook, Photos) and then -if he likes- even wipe it.   

So if you don’t need OpenSSH, make sure you deinstall it!

Side node: You could also change the root password of your iphone, but I heard that some people have problems after doing so. So its safer just to deinstall OpenSSH, if you don’t need it anymore.

For many people just changing the APN settings to something random still works to disable EDGE on iPhone 2.0. However, if your SIM card is from a supported carrier, the iPhone will not present any settings to let you change the APN configuration. I found a quite easy way to disable EDGE even on those phones. You don’t need the terminal, a jailbreak or something else for it..
The only thing you have to do is to download the following file:
Profile for disabling EDGE

Next attach this file to an email and send it to an account you receive on your iphone. Open the email containing this file, click on the attachment. You will be presented with a screen that shows you some information. Click install and the APN settings are changed. EDGE should now be deactivated. An alternative way is to download the file directly from MobileSafari.

How can you create this profile yourself:
1. Download the iphone configuration utilitiy: Download This is an offical, free Apple tool.

2. Create a new “Configuration Profile” and click on the “Advanced Setting” to set the APN information for EDGE. After you have done that export the profile, send it per mail to your iphone and install it as described above.

Hint: To switch EDGE on and off just create two profiles and save them in a folder in your mailbox. Just by selecting the right profile and installing it you can enable and disable EDGE.
I hope that helps all of you using the iPhone without a flatrate for data.
