I went to: BlackBerry
Click on Support
Click on Downloads on the left side
Click on BlackBerry® Device Software and BlackBerry® Desktop Software
Click on Access your service provider download site
Click on Sprint L.P.
Select Blackberry 8830 Wireless Handheld (TM) and click Next
My connection hasn't dropped since updating but I haven't used it much either. The person above said it didn't help though so I am not holding my breath :(
