Another week, another slew of iPhone rumours.

The first thing of note is that we've heard from an exceptionally reliable source that the iPhone 5S will, as expected, be launching in June of this year. You can read all about what we're expecting from the next version of the iPhone here.

Whilst we're on the subject of iPhones, we're hearing more rumours every day about what to expect from the iPhone 6, which we're expecting to launch in 2014. The latest bit of speculation to catch our eye is that it will include indoor location mapping. What use is that to me, we hear you cry? Well, GPS, and therefore mapping apps, won't work indoors because the roof gets in the way of the GPS signal. Indoor mapping is powered by using wifi networks rather than satellites, so it overcomes the problem. Indoor mapping could come in handy when trying to navigate your way round a large store to find what you want, or a shopping centre. You could even use it to keep tabs on your kids location - as long as they were all running around with iPhone 6s in their pockets, of course.

Of course, the big rivals to Apple's iPhone are Samsung's Galaxy range of smartphones, including the recently launched Samsung Galaxy SIV. Of course, we shouldn't just expect one SIV - the SIII had an iPhone-sized, mid range little brother called the SIII Mini. So we're fully expecting a SIV Mini to launch soon, although rumour has it that they'll be more than one variant. In this case, they'll be a 3G version, a 4G version and a dual SIM version, although whether all of these will reach the UK market has yet to be confirmed. We've also heard that the SIV Mini won't be as much of a step down in terms of specs from it's bigger brother than the SIII Mini was from the SIII, which would be good news when and if confirmed.

Talking of the Samsung Galaxy SIV, Chinese manufacturer Huawei is apparently lining up a direct competitor offering to launch at more or less the same time. The premium handset is expected to have high specification innards, a 5.9 inch 1080p HD display, a 13 megapixel camera and be an extremely svelte 6.3mm thick. And knowing Huawei, it'll be a bargain too. Watch this space

And finally, check this out. It's the world's smallest smartphone charger. At least, it will be if it can get funding on Kickstarter.

It's tiny 'petrol can design is so small it can fit on your keyring. And it can 'juice up' your smartphone in an emergency up to about 1/7th of its battery capacity. That's enough to give you about 20-30 minutes of extra talk time, or a few extra hours of standby time. As an extra bonus, the charger holds its own charge for up to 3 months, so you don't have to remember to charge it that often. The only downside is that it's not compatible with iPhones at the moment, although a version that is is planned. We think it's a great idea, and if you'd like to fund it you can make a contribution here.
