Because of Apple policies, the VoIP software can use WiFi connections only and not 3G.
In other words you can not make skype calls on the road.
In order to do it, this is what you need:

1-Your iPhone must be jailbroken, if it’s not, read this.
2-Install your Skype or Fing app from the App Store.
3-Install 3G Unrestrictor from Cydia.
4-Open 3G unrestrictor and add the desired applications (skype, fringe, whatever you want)

OK, now is beginig to be possible to sync your music from Ubuntu to your iPhone, thanks to the work of marcan and many others.

Disclaimer: This is very Alfa software, I didn’t invented any of the things I’m writing about, I just adpated the marcan instructions in the way they worked for me, to my personal systems, wich I’m sure many are using: Ubuntu Karmic Koala 9.10 and iPhone 3G with OS 3.1.2, by the way you need to have some music synced by iTunes before you can start.
Don’t cry if your iPhone melts:

1- update your system, either via synaptic or with

sudo apt-get update

sudo apt-get upgrade

2- Add the PPA repository with the needed packages :

deb http://ppa.launchpad.net/jonabeck/ppa/ubuntu karmic main

Either adding it as root to your /etc/apt/sources.list file

Or with the GUI “Software sources”

Then add the key for the repo with this command:
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com F0876AC9

And update again with:

sudo apt-get update

3- Install the packages required for compilation, and the already packaged libraries:

sudo apt-get install git-core cmake autoconf libtool libglib2.0-dev intltool gtk-doc-tools libsqlite3-dev libxml2-dev  libiphone-dev libplist1 libusb-1.0-0 libusb-1.0-0-dev libusbmux0 libusbmux-dev ifuse libiphone0 libplist0 libplist-dev

4-Get the libgpod code and compile it:

$ git clone git://gtkpod.git.sourceforge.net/gitroot/gtkpod/libgpod
$ cd libgpod
$ CFLAGS=”-g -O0″ sh autogen.sh –prefix=/usr
$ make
$ sudo make install

5-Create a folder to mount it, and mount it:

sudo mkdir /media/ipod

**connect your iPhone**

sudo ifuse /media/ipod

6-Create the needed directory and files:

cd /media/ipod/iTunes_Control
mkdir Device

Find your UUID with

lsusb -v | grep -i iSerial

grab your UUID wich is the 40 characters long text
and run the following command replaceing with yours:

ipod-read-sysinfo-extended /media/ipod

This has generated a needed file into the Device folder.

7-Thats it. Now you can open the gtkpod application and sync your iPhone.

Notes:
In order tu unmount your iphone first dissconect it via gtkpod and the you can use

sudo umount /media/ipod

And to mount it again just

sudo ifuse /media/ipod

There is a way to sync your files in the iphone, and also shering not only with ubuntu, but also with Windows or Mac.

It’s a free service called dropbox that offers 2Gb of space for your files.

1-Click here to go the dropbox website and create a free account.

2-Click on the Install link to Download dropbox and install it on your PC, there are versions avilable for Ubuntu, Fedora, and Sources (there are also Windows and Mac versions).

3-On Your iPhone go to the Apple Store and search for dropbox and install it.

4-Now You have a Dropbox folder in your PC, and a Dropbox app in your iphone. Any file that you copy to your Dropbox folder will appear on your iphone, and viceversa.

Have fun!

I recentyl posted a way to get rid of the “This Copy of Microsoft Office is not Genuine messages”, that  involved getting rid of Microsoft Office itself and replace it by OpenOffice.org and Thunderbird, That is the preferred Method.

But if you are a Microsoft Lover and want to get rid only of the messages, and keep using Microsoft Office then this is what’s needed:

1- Close all the Microsoft Office Applications

2-Use the File Explorer to Navigate to your Windows System installation folder, usually:

C:\Windows\System32

or

C:\Windows\SysWow64  -for 64 bit systems-

And then locate and remove (just rename, if feel fear) the following files:

OGAVerify.exe

OGAAddin.dll

3-Ready! Start any Microsft Office, and you will see that is fast again and no more annoying messages.

As we all know evrytime windows does not properly work (and that’s very often) we have to use Ctrl+Alt+Del, so how to do it if you are accession Windows from a Remote Desktop Connection:

From Windows: Press Ctrl + Alt + End

From Linux: Press Ctrl + Alt + Del (yes, because its harmless to linux)

From MAC: Press Ctrl + Option + ForwardDelete

From iPhone: If you are using JaaduRDP, select the top icon with the arrows, slide to the second windows, there you’ll see it, just click it (and close the arrows icon again to go back to the desktop).

When an iPhone is jailbroken, and OpenSSH server is installed in order to provide remote access.

There are two accounts root -the superuser- and mobile -the standard user-.

Both accounts have a default password: alpine

In order to change the passwords you can do it via regular Linux commands:

• Access the iPhone via ssh from your PC (you can install putty on windows to do this)

ssh root@your.iphone.ip

Note: If this is the first time you connect this PC to your iPhone you will see a warning abiout fingerprints, say yes.

• and type the passwd command, it will prompt you for your password twice, when you type your new password nothing will be prompted:

passwd

• type exit to dissconnect

exit

• Repeat the steps but this time for mobile, start with:

ssh mobile@your.iphone.ip

I have a previouse post about how to jailbrake an iphone but now it may be diffrent, there are two publishers of jailbreaking applications: the Dev-Team and geohot (any other source you find is just selling what they give for free).

Well, geohot has published a new app called blackra1n, this is definitivelly the fastest jailbreak I have ever seen. Not even a how to is really needed, just go to his site, download, run, follow the onscreen instructions (basically, click, connect, and wait)

And have fun!

Ubuntu netbook remix includes maximus, which is an application that maximizes all the new windows and removes the decoration, this is is very good to make it easier to work with small screens, and even to save space in regular screens, the last is my case…

Well but sometimes maximus might annoy you because it maximizes all windows, even the ones that where designed to be small.

There is no maximus icon or preferences at first sight, but you can find it under the hood, via the gconf-editor:

So open the gconf-editor with the command:

gconf-editor

open /apps/maximus

You will see some options, that can help you to select applications that you don’t want to get maximized, you can keep decoration, and you can stop automatic maximization…play with that.

(Acrobat Reader is no longer in the medibuntu repository)

If you have upgraded to Ubuntu 9.10 (karmic kola) and want to install Acrobat Reader (acroread) you have to enable the canonical partners repository:

Go to the GNOME Menu : System > Administration > Software Sources

Select tab Other Sources

Mark: deb http://archive.canonical.com/ubuntu karmic partner

Reload your sources, either graphically or with:

sudo apt-get update

And then as usual simply install acroread via synaptic or with the command:

sudo apt-get install acroread

As a Linux fan, every time a new version of my current favorite distro -ubuntu- comes out (every six months) I download the ISO image burn it into a CD an perform a clean install. So I got a bunch of CDs, that I don’t really need after installation.

But not any more. This is what’s needed to do it from a USB flash drive and stop the CDs to pollute:

1. Download you ISO.
2. Install UNetbootin:
   

   sudo apt-get install unetbooting

3. Start it from Applications>System Tools>UNetbootin
4. Select your ISO file, and click on Accept.
5. One the USB is ready, boot from it and install Linux as yoiu would do it from the CD.

Notes:

1-UNetbootin Runs also from Windows

2-UNetbootin can download the ISO for you, but of course if it’s too know it migh not appear in the list…
