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)


Ready

By defult the Skype iPone App does not support Video.
But there is simple workaround: Use Fringe.

First you must have a
account

Then from your iPhone go the App Store, search fring and install it.
Open the fring app to open a fring account.

Ready now you have skype with video.

Celular rates are expensive everywere and international fees too.
So, how to make cheap international calls from your iPhone?
Simple, use


Click this link and get Up to 10,000 calling minutes to landlines for one low monthly fee – the new Skype calling subscriptions.

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!

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).

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.

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…

There are not technical reasons, only Apple marketing policies, but the iPhone is not allowed to run multiple applications simultaneously , by design only the phone, mail, ipod, and maybe some other Apple application can run in the backgroud.

This is of course not the desired behavior for many cases…

Multitasking you can, for example:

• Have a messaging service available at any time.
• Have an IP phone (e.g. skype, gizmo5) available all time.
• Pause a game,  go to write an email, read the news, and go back to the game…etc.
• etc

So this is what’s needed to enable Multitasking in your iPhone:

1. In order to enable it, the iPhone must be jailbroken, if  it’s not, there’s a jailbreak how to here.
2. From Cydia (or Icy), search and install the backgrounder app. This will provide the availability to run applications in the background.
3. From Cydia (or Icy), search and install the application kirikae. This will provide a task manager that will let you switch between open applications and close them. You can also add favorite apps to open faster.
4. Have Fun

Usually,  you want to use your phone as a modem to provide internet access to your laptop, but there are somecases were you want the opposite, e.g. I’m in a foreing country, with no wifi internet, just wired access, how do I get my iPhone into the internet via WiFi and avoiding the muche expensive data roamig bucks? This is what I did:

I’m Using Ubuntu Linux and an iPhone.

-Connect the laptop to the wired internet.

-Click on the NetworkManager Applet

-Select “Create New Wireless Network…”

-Give a Name (e.g. MyOwnWiFi)

-If you want give a security option (e.g. WEP) and provide a password.

-Connect the iPhone to the new Wirless Network (no changes required, this shuld work in standard DHCP mode)

Ready to go.
