I bought my play book some time ago and have had a very good time with it. I do have a problem with native email. My playbook deletes old emails and probably only keeps for last couple of weeks. I have been to all the setting and set up options to keep emails for ever but it doesn't work for me. Any one can help ?
What type of email are you using? A web based service like Gmail or perhaps an account associated with a web service with something like a pop3 service?
