I understand the BIS polling times, however I seem to have a BIS polling issue. During the night, I seem to receive no emails to my BB. The BB is powered on, I have signal just as it is during the day.
When I wake up in the morning, I will start to check the weather, facebook, etc... Then I will get my mail. This morning I received no emails during the night, and then received 67 emails once I started my morning browsing. Any ideas?
