Apple chief Steve Jobs today unveiled a new iPod range in San Francisco, describing the new nanos as the “thinnest” music players ever produced by the iconic tech company.

Despite being the “thinnest”, the new iPod nanos also sport a built-in speaker. Check out Engadget for some cool photos.

The wire agency AFP also quoted Jobs as saying that Apple will release the iPhone 3G 2.1 update this Friday (Sept. 12).

Reuters meanwhile reported that:

Jobs introduced a curved aluminum and glass nano — the best-selling iPod — for $149 with 8 gigabytes of storage, $50 less than the predecessor model and a 16-gigabyte version for $199, with up to 24 hours of music playback or four hours of video. He also rolled out a thinner, $229 version of the Internet-connecting iPod touch with rounded edges and 8 gigabytes of storage.

The SF event also marked the introduction of “a second generation iPod Touch, with built in support for the Nike+ jogging accessory. The new Touch is substantially less expensive, at 229 (8GB), $299 (16GB), and $399 (32GB), and now shares the iPhone 3G curved design”, which TechCrunch has initially reviewed.
