BB Software :: Cant Add Nor Edit Contacts Since Added Gmail Account

Time ago I´ve used to have only 1 mail account set on my blackberry, a gmail account (xxxxx@gmail.com), and used the google sync (url...) to synchronize contacts between the smartphone and the webmail account. It has been working like a charm for a long time. At that time, I could create and edit contacts and the changes got synchronized in both sites.A month ago I decided to create through Google Apps an email address with my own internet domain (xxxxx@xxxxxxxx.com), and decided to add this email address to the smartphone to check both accounts. The first surprise came when I noted that adding this email address (following the procedure to add any email address) has caused the BB to activate it, like BES mode, against the gmail server.Suddenly I discovered that I cant create nor edit contacts in BB, but I can in the webmail interface of the google apps email address. The contact created using the web interface is syncronized to the BB.The issue is that I cant create nor edit contacts in the smartphone!
