How to export Address Book from Blackberry to Samsung Vibrant

How to export Address Book from Blackberry to Yahoo Contacts

Using the Blackberry Desktop Manager, I connected my phone to the computer. Once the connection has been established, here's how to do it. I'm not sure if this is the quickest way, but it doesn't take that long and is very easy to do:

Open up a Yahoo account if you don't already have one (it is free). Open up desktop manager, connect to your Blackberry and double click on "Synchronize." Go to the "Configuration" tab, and click on "Configure synch." Click on "Address Book" and then the "Choose" button. Select "Yahoo" and "Export," then back to the main Syncrhonize window. Click the "Syncrhonize" tab, make sure "Syncrhonize Organizer Data" is on, then press "Synchronize now." Now go to address. yahoo. com. In the upper right corner, click "Import/Export." Under Export, click the button next to "vCard, Zip of .VCF files," and save the .zip file. Now save the file into your computer's hard disk. Create a folder in the SD card of the Samsung Vibrant and unzip all the vCard files contained in the zip file into the folder you have created. Now you are set to import the vCards into your Samsung Vibrant.

Importing contacts to Vibrant

In Contacts, go to Settings>More>Import/Export

Export the contacts to SD.

Then go Import/Export

and Import them from SD to phone.

Wait for the phone to read the vCards from the SD card. Follow screen instructions.

Then, when you select a Contact, and choose edit, you will see 2 tabs at the top; Your Gmail syncs and Phone. Choose the Phone tab, and you'll see all of the contacts. Then when you choose to edit one, the option to choose a ringtone, group, etc. for each contact will be available to you.

Then, if you so choose, you can choose the View option under settings, and uncheck the gmail contacts, and leave only the Phone contacts viewable (unless you also have facebook, etc. contacts you wish to be viewable as well).

In any case, I think this should work well for you.

Error: Can't load netbeans when Java after jdk change

If you can not load Netbeans because it can not find Java, just edit this file and put the correct path of java


# ${HOME} will be replaced by JVM user.hit ome system property
netbeans_default_userdir="${HOME}/.netbeans/6.8"

# Options used by NetBeans launcher by default, can be overridden by explicit
# command line switches:
netbeans_default_options="-J-Dorg.glassfish.v3ee6.installRoot=\"C:\Program Files (x86)\sges-v3\" -J-client -J-Xverify:none -J-Xss2m -J-Xms32m -J-XX:PermSize=32m -J-XX:MaxPermSize=200m -J-Dapple.laf.useScreenMenuBar=true -J-Dsun.java2d.noddraw=true"
# Note that a default -Xmx is selected for you automatically.
# You can find this value in var/log/messages.log file in your userdir.
# The automatically selected value can be overridden by specifying -J-Xmx here
# or on the command line.

# If you specify the heap size (-Xmx) explicitely, you may also want to enable
# Concurrent Mark & Sweep garbage collector. In such case add the following
# options to the netbeans_default_options:
# -J-XX:+UseConcMarkSweepGC -J-XX:+CMSClassUnloadingEnabled -J-XX:+CMSPermGenSweepingEnabled
# (see http://wiki.netbeans.org/wiki/view/FaqGCPauses)

# Default location of JDK, can be overridden by using --jdkhome :
netbeans_jdkhome="C:\Program Files\Java\jdk1.6.0_21"


# Additional module clusters, using ${path.separator} (';' on Windows or ':' on Unix):
#netbeans_extraclusters="/absolute/path/to/cluster1:/absolute/path/to/cluster2"

# If you have some problems with detect of proxy settings, you may want to enable
# detect the proxy settings provided by JDK5 or higher.
# In such case add -J-Djava.net.useSystemProxies=true to the netbeans_default_options.

Fix / Restore Fedora 15 GRUB Boot Loader

Unfortunately, maintaining a multi-boot configuration like this can be a pain, especially if you later install an operating system which overwrites the GRUB boot loader you had in place (such as a version of Windows). If your boot loader is overwritten, you could be left with no choice but to boot the most recently installed OS.

In this tutorial, I will show you how to restore an overwritten copy of the GRUB boot loader by using a Linux live CD. In this example, my master GRUB installation is on a Fedora 15 installation, and I’m using a Fedora 15 Live CD to boot the system.

Start the Live CD up as normal. Don’t choose to install the OS if prompted, you want to come to a full live desktop to run the specific commands we need.

1. Identify your Partitions

Open a Terminal program and use the following command:

[alexm@localhost ~]$ su
[root@localhost /]# fdisk -l

Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x4b474b47

Device Boot Start End Blocks Id System
/dev/sda1 * 2048 206847 102400 7 HPFS/NTFS/exFAT
/dev/sda2 206848 91394047 45593600 7 HPFS/NTFS/exFAT
/dev/sda3 91394048 402077695 155341824 83 Linux
/dev/sda4 402077696 976771071 287346688 f W95 Ext'd (LBA)
/dev/sda5 402079744 976771071 287345664 7 HPFS/NTFS/exFAT
[root@localhost /]#

If you can work out where your Linux is from this, note down the information under ‘Device’.
In this tutorial, Fedora 15 is installed in /dev/sda3

2. Run grub-install
[root@localhost ]# sudo -i

[root@localhost ~]# mount /dev/sda3 /mnt

[root@localhost ~]# grub-install --root-directory=/mnt/ /dev/sda
Installation finished. No error reported.
This is the contents of the device map /mnt//boot/grub/device.map.
Check if this is correct or not. If any of the lines is incorrect,
fix it and re-run the script `grub-install'.

# this device map was generated by anaconda
