Fido

Hi,   Does anyone know if it is possible to update the Blackberry OS to 6.0 on the 8520?  Will it cause problems with Fido?  If not, how can I get the software, or when will it be available?   Thanks.     ***Edited to add labels***

Hi,   Since I've had my phone, the GPS is not working.  If I go into Advanced Options | GPS, the only option for GPS Data Source is None.  Is this a limitation of my plan, or is my device malfunctioning?  What do I do to resolve this?   Thanks.     *...
