I've got two questions for you savvy folks here today.

I own a BlackBerry Curve 8320 and want to know if it can be used as a modem for my laptiop computer.

Also, for this model, what is the highest micro sd card recommended for use?

Yes you can use your device as a modem. You may need to add a tethering feature to your account.

The size of the media card is limited by your OS.
