One of the best things about the iPhone 4 is that it packs a lot of power into a small handset. The problem with this is that the smaller a device is, the easier it is to lose. Also the more information we store on the smartphone - such as emails and website login details - the more damaging the loss of the iPhone will be.

Kensington has come up with a rather clever method of securing your iPhone 4. Taking its cues from remote car locking systems, the Kensington BungeeAir Power Wireless Security Tether for iPhone comes with a special iPhone 4 case and key fob.

From a distance, you can click to lock the phone remotely. Even better, once you've moved the key fob a certain distance away from the iPhone, an alarm will sound, so you'll be reminded if you've left the phone behind.

It works rather well, using wireless 2.4GHz technology, and through the BungeeAir app you can control the distance and other security features. If someone tries to remove the case from the iPhone, the alarm will sound as well, alerting you if your phone is being tampered with.

You can also use the key fob to set the phone to ring so you can quickly find it. A great feature is that this works both ways, so if you've lost your keys you can use the iPhone to 'ring' the key fob, helping you locate them.

Another nice feature is that the case not only provides security, it can also be charged to provide around three hours of extra battery life.

Verdict

If you're the forgetful type, you might find the Kensington BungeeAir Power Wireless Security Tether for iPhone a very handy piece of kit indeed.

The RadTech 'Bezel Blaster' is an over-the-top title for what you get.

It's basically a rough refinishing pad with a fine sandpaper texture for fixing scratches and blemishes in worn and tatty iPods and iPhone bezels (chrome finishes only), and a cloth for buffing up.

It doesn't actually eliminate scratches, but gives you a more consistent scratch pattern by sandpapering them out.

It takes away the shine as well as the scratches, so don't use it unless you want a brushed-metal finish.

This is a 14K gold-plated bezel for an iPod touch that has a continuous row of Swarovski crystals encrusted into the upper edges to create a diamond effect.

The underlying grooves of the bezel, the part that the iPod slides into, is a softer, lined material with a rubberish feel.

Poor build quality

We'll spare you our snobbish rants about the type of WAG – sorry, consumer – this product might appeal to, and tell you that the bezel did fit an iPod touch and did do its glitzy job.

On the downside, the build quality is weak compared to other iPod cases we've seen. The metal bends easily and the rubber lining started to flake away quite soon after we started using it.

If you're looking for a glam hit, and (pass the smelling salts) think that this product in some way improves the look of an iPod touch, then by all means go ahead and buy it.

Gilty Couture has a range of similar items for other iPods and the iPhone that can be browsed on its site. Fashion is not really our forte, but we suspect this might go well with a Burberry tracksuit.
