Over the past few weeks I have noticed at least three occasions where my BB Pearl has lost its BIS connection. This doesn't seem to match up to any service issues that I have heard about at RIM's end. I only notice this when the icon for a weather program I have installed turns generic instead of showing the current weather. In order to fix this I need to reset the BB with a battery pull. Has anyone else noticed behaviour like this? I'm using Bell Mobility.
