Amazon has updated its mobile shopping app with a feature we're amazed took this long to implement. The latest version of 'Amazon Mobile' for the iPhone now supports barcode scanning
for quickly finding prices. You can now easily order whatever you've scanned from Amazon without needing to wait till you get back to a PC. This is really handy for comparison shopping while you're out and about -- you can scan bar codes to see what premium you're paying for a gadget from Best Buy or a book from Barnes & Noble. Outside of the new enhancement, it's the same 'Amazon Mobile' (iTunes Download
) app you've come to know and love. Sadly, only 3GS and iPhone 4 owners can use the barcode-scanning features.
