On Gmail, BB 9900 seems to have problems syncing with Gmail.

I used two messaging folders. The default BB Messages folders is where my yahoo mail accounts go. I then hide all the yahoo mail icons.

Then I separated my GMail account not to appear in the default Message folder. So now i have two mail folder icons - the default folder and the gmail icon/folder.

Oftentimes, when I try to Delete Prior Emails in my gmail account, one or two mails remain and cannot be deleted.

I tried to go to View Folders and discover the "undeletable" mails under [Gmail]/Important. I tried to delete from there but it won't delete.

I noticed also that it is always the "group" message (where all messages under the original thread is grouped) that is the culprit.

Any help please?
