Now i've tried to create some new groups on the phone, just to play around a little to see what happens.
But i cant seem to sync with google anymore. I have gotten the "sync not available, back shortly" error for some time now.
I have finally got it to work.
First, i had to solve the problem not being able to sync. To do that i went to settings->programms->administer->contacts. Here i cleared all data (will delete all contacts on phone)
Now i could sync again, but still got all the email contacts on my phone also. And now i was missing the option to choose seperate groups. Everything google was gone. I could only create phone and sim contacts. So...
Second, i went back to settings->programms->administer->Google apps, and cleared all data here as well. Then i went to settings->datasync->google, where i was asked to re enter my google login.
All this resulted in the returning of google options to my contacts. So i could finally choose specifik groups that i wanted to sync. And VOILA
Its weired, when i pressed "menu" while i was in contacts. I had several different options, before re entering my google info. There was even a "more" button, wich besides others gave me the option to sync with google.
But after clearing the data of google apps, that button is gone.
Android is great, but it seems that too many different people put their options in.
