Hi, Sammy! Too bad to hear that you didn't like the Nokia E71. Lucky us, then! ;)
Anyway, one of the cool things I'm enjoying on the trial Nokia E71 device is using the Barcode reader software, which reads 2D barcodes. If your Nokia device doesn't come with it, check out this link. At first, I couldn't get it to work, but once I put the camera over a QR code, voila! the website address comes up and it's very cool! You've got to try it to see it! Now, I'm looking for those QR codes and get them scanned!
You can also get a lot of other barcode scanning apps besides the one built-in. You've got to check it out! There's also QuickMark for the Windows Mobile or the i-nigma (haven't tried either yet).
