The danger of Bluetooth headsets is that passers-by might not spot them and may assume you're randomly jabbering at them or worse, to yourself. Flying in the face of this danger, and at the risk of sounding like a Bodyform advert, Celleden has released a headset so discrete, even you may not notice you're wearing it.

Barely bigger than a piece of loose coinage, as the photo attests, it weighs in at a measly 6.5g. yet manages 4hrs talktime and 50hrs stand-by - all topped up by its handy charging stand.

The press release proclaims that: "users can rest assured that wearing one will not damage their street cred!" For those of us who any to damage, that is.

It's available now in black or white for £29.99 from twistedcarbon.com and 'selected' high street stores.

Last week, the online forum notebookreview.com unearthed the first details on Sony's rumoured SR and FW series - now it appears to have found confirmation. Both laptops have shown up on Circuit City's website. They were swiftly taken down, but not before several people managed to save the pages.

The 16.4in Sony VAIO FW, shown in white, is a multimedia-savvy laptop designed to replace the FZ series. Circuit City listed it as shipping with a 2.26GHz Core 2 Duo T8400, 4GB DDR2 RAM and a 250GB 5400rpm hard drive for $1149.99 - that's without the optional Blu-Ray...

Murmurs appearing on Taiwanese site Digitimes are suggesting that Asus is about to launch two new Eee PCs that fuse the current 900 series with the new 1000 (pictured).

By keeping the same 8.9in screen of the 900 but placing it in 10.2in the body of the 1000, Asus hopes to create two inexpensive 8.9in models with more practical, larger keyboards.

The 904 and 905, as they've been dubbed, would get Intel Atom processors, and possibly larger batteries and greater storage.

Oddly, Digitimes sees them as eventually replacing the current 900 and 901 models, which seems a somewhat bizarre move as it would leave Asus without a true 8.9in sized laptop. Happy times for the competition should that happen.

It may only just be catching up when it comes to mobile broadband but when it comes to surfing at home, it appears others are scrabbling to catch up with O2. It's come top of moneysupermarket.com's quarterly speed tables with its 8Mb service, which is offered at a discount to O2 customers, averaging an actual speed of 5.39Mbps.

Second and third were Sky and TalkTalk with a disappointing 3.59Mbps and 2.99Mbps, but still way ahead of some of the rest of the competition.

Best value were some of the 2Mb packages, which average around £10 a month but generally deliver what they promise, with the average speed actually just over the stated rate at 2.11Mbps. O2 doesn't have a 2Mb package, but Sky and TalkTalk both offer ones free to their customers.

Poorest performers when it came to delivering advertised rates were high speed packages. O2 again came top, but could still only average 8.15Mbps for its 16 and 20Mb offerings.

Of course, fibre optic broadband gets round this fall-off issue but only Virgin and a handful of small providers currently offer it.

With all the issues with Eee PC's batteries, owners might well have stocked up on a spare to keep them powered up. Only problem is - how do you charge it? Asus only provides the option of charging the battery while it's strapped to the Eee itself, making it tricky to keep a spare topped up at all times.

Enter Expansys, which has come up with a battery charger for 700/ 701 Series cells and 900/901/1000 Series ones.

They're for pre-order at the moment with no due date - but the US site has got them pegged for arrival on 31st July.

If you're thinking of offloading your original iPhone on eBay or to a family member come iPhone 3G launch day on 11th July, you may want to upgrade the software to version 2.0 first.

Appleinsider.com has spotted that the new update now securely deletes all data when you hit 'erase iPhone'. Previously, iPhone only binned the information, leaving it open to being 'unbinned' and accessed by anyone with the right know-how.

Now the software does a popper spring clean by overwriting your contacts, photos and other precious details with random strings of ones and zeros. It does mean the process takes a tad longer but, short of having a buddy at the Pentagon, it's all but impossible to reverse. So no worrying about whether the text messages you sent your ex will crop up on the Internet. We'll sleep easier tonight.

RIM’s BlackBerry was the first smartphone to bring the delights of instant, push email to the business masses and it has been much copied over the years. No manufacturer has taken it quite to the same extreme as Toshiba, however, whose Portégé G710 apes not only the BlackBerry’s slab-style Qwerty keyboard, but also the navigation method.

The rest of the world may have already reviewed the shiny new Diamond Windows Mobile smartphone, but HTC UK only got around to issuing review models to UK journalists last night.

So, since we have a new video camera to hand, we thought we’d shoot a little clip of – yes – the HTC Diamond box being opened for the very first time! Thrill at the novel pyramidal frustum prismatoid packaging! Gasp as the clear plastic protective strip is peeled away from the smartphone screen! Gaze in awe as the two parts of the cunningly designed mains adapter are clipped together! All that stuff, and more, after the cut.

If all the snippets you’ve read about Opera Mobile 9.5 have had you hankering for this next generation Windows Mobile web browser, here’s a bit of good news – the first beta will be available for download on 15 July.

Opera 9.5 is based on the same browser engine as the recently-released desktop version of Opera 9.5 and, judging by the information we’ve seen so far, should be the best handheld web browser since Safari on the iPhone (though we have high hopes for the imminent Firefox Mobile, too).

Echoing Carphone Warehouse's AOL offer, Phones4U has come up with a similar deal to flog Orange mobile broadband. Customers signing up to Orange's 3GB tariff for £30 a month can snare a 15.4in Fujitsu Siemens Esprimo (pictured) worth £349.99, complete with Intel Celeron 540 Processor, 80GB hard drive and 1GB RAM - together with the free HSDPA modem.

If that seems a bit weedy for your mobile tastes, there's also the option to upgrade to a 120GB Samsung R60 worth £499.99 for a modest £74.95.
