WI-FI problem..

Hey all...wifi status shows connected (says ROGERS - HOUSE) at the top, but the wifi symbol is still grey and won't turn white - from what I understand, this means I can still surf the net on wifi but and Blackberry services (BIS) aren't connected through wifi. I had an 8900 and it worked perfectly but it won't seem to work on the 9700. I have talked with tech support for hours, they've sent me a new phone, I've tested it on different wifi's, etc but nothing seems to work...any ideas?

:confused:
