Hi,
After I updated my Xperia Arc with the android version 2.3.4..I am unable to join contacts. Whenever I tap the option Join contacts it gives me error "The application Contacts(process com.sonyericsson.android.socialphonebook) has stopped unexpectedly. Please try again.".
I install and uninstalled many application so its hard to track whether any specefic one is causing the issue.I have tried rebooting the phone.But still the problem is persisting.Is there any fix for this??
first backup all your contacts..
press the menu buton in contacts and select backup.. save them to sd
then go to settings > applications > manage applications > all > contacts
then clear the data
go back to contacts , press menu button and select import contacts
then try to join..k..
Please do try the above, however if this does not work you may need to look at running a repair via PC Companion as it appears the Update did not apply correctly to the phone.
I tried export and import the join still fails and my contacts are all messed up :smileyangry:. All of them are now unjoined and i am unable to join them back its like 1300 contacts in my phone book now 
sync them to gmail/google then edit them on your computer -> delete them all from your phone and sync your contacts from google
Contacts
just to play it safe sync your contacts w/ google if you haven't already
open your phonebook
press MENU button -> tap on Send Contacts -> select all -> send it to your email
on your computer
-> download the file -> go to your gmail -> click on contacts -> click on more actions -> on the drop down menu click on "import" -> choose the file -> and click import
try the above method then 
I just tried a thing .. when i long press on a contact and bring the menu then select the join contact option, it is failing each time..but if i go to a contact>edit>join contact it is working for 90% of the time... should i still go for running repair 
I would just sync them to google and join them on your computer, it's a bit easier and faster then repair your phone, just in case it's a bug on your software
make sure to backup everything
Settings -> privacy -> Back up my data and Automatic restore should be selected
and also
Use one of these links to download the

Hi Everyone,
Finally sorted the problem out.. i had an app "GO launcher EX" installed. I just noticed on a video that my list of options are different that what by default are there (was watching a video on Youtube for ARC.. lucky me) .. So I uninstalled the app and here I am sitting all happy :smileyblush:.
For the contact I cleared the contact storage application data and then imported the vcf again that i saved as initially suggested.For now atleast I have all the phone contacts with me :smileylaugh:.... (smile turning to grin
).
I guess i'll sync FB accounts when i am back at home in range on my wireless connection.
Thanks everyone for there valuable suggestion.
