Barcode Scanner and speaker

[beetat]

When scanning something at supermarket, does it actually tell you what store you can purchase the item cheaper for or does it just send you to websites?

Also, how can I talk on phone using a speaker (when driving)?  Where is it?

re scanning bar codes... depends on the application. I use ShopSavvy which provides a list of local merchants and web sites.

During a call, touch the Speaker button in the phone app.
