If you’re an iPhone user, you probably have three main concerns that occupy your mind: having your phone stolen, dropping your phone and your phone running out of battery. Depending on where you live, strapping your iPhone to your arm in a highly-visible-to-thieves fashion as you head out for a run may not be the wisest thing to do, in which case the Belkin iPhone 4 fastfit armband is probably not for you. In the interest of safety I checked the Met police’s latest stats on jogging-related iPhone thefts for my postcode before I set of and decided the odds were in my favour.

I’ve used a similar Belkin product for my Nano and with that the Nano slides into a pocked on the armband from the top. With the iPhone 4 armband you insert your phone from the bottom – you know, the way gravity will pull it – and secure it with a Velcro flap. Although this flap seems secure, anxious iPhone users like myself are going to spend a good proportion of their run wondering if the next swing of their arm will result in their phone flying out. But then maybe it will reign in any wild arm movements and help my running form. It did stay in place but I’d be much happier if the phone were inserted from the top (you can’t just turn it upside down because of how the case fixes to the armband).

So to point three – the battery life of the iPhone. This isn’t really down to the Belkin but the iPhone itself. But if it’s not worth taking your phone for a run then you don’t need the arm band in the first place. I was surprised though that using the iPhone 4’s iPod for my 45 minute run only used up 3% of my battery, so it won’t need topping up before a run. So if you’re more relaxed about getting your phone robbed or breaking it than I am, give it a whirl.
