Apple Inc unveiled the iPhone 5 thinner and lighter than the previous model, even though it has a bigger  Retina display on the 4-inch touchscreen.

iphone 5 have 16, 32 or 64 gigabytes Memory capacity , depending on price. There’s no way to expand it with memory cards.

iPhone 5 thinner 0.30 inches, 4.87 inches high, 2.31 inches wide, .3 inches thick and a weight of 3.95 ounces.

the first size upgrade since the phone debuted. This means a taller, larger screen. There is a 1136×640 resolution, or 326 ppi. There is a fingerprint-resistant coating on the front.

Based on the roadmap of mobile chip design specialist ARM (of which Apple is a licensee), we’ll see a quad-core processor debut in the new iPhone 5 – probably called the Apple A6. We’ve seen other quad core handsets debut in 2012, so it’s not too much of a stretch to say that the new iPhone 5 will be the same.

We had expected some kind of help in terms of predicting the iPhone 5 CPU from the launch of the new iPad, but the announcement of a slightly tweaked A5X processor really didn’t help things there.

According to a tip to 9to5Mac, the CPU will be the S5L8950X. Again this could be a derivative of the A5, but as 9to5Mac points out, Apple is probably working on a low-power 32nm version of the processor. As we could well have guessed, that processor will be manufactured by Samsung but designed by Apple itself.

New photos have shown what some believe to be the new internal chipset, which features an A6 power unit, which may up the level to quad-core power – or could be more to allow things like NFC on board too.

Alternative other pics have hinted that we’re just going to see a dual-core power unit, which would fit with previous Apple strategy of not always going for specs…many believe dual core chips are still powerful enough, and Apple could definitely follow suit.

The same report suggests 1GB of RAM, which seems right to us. Other recent reports suggest that Apple is trying to ditch Samsung as a supplier for the iPhone 5′s DRAM and NAND chips – but it’s nothing to do with the two companies’ patent battle, honest.

Images of a range of internal gubbins, all claiming to be parts of the iPhone 5, have made their way onto the internet – possibly revealing more about Apple’s sixth generation handset.

These are interesting for a number of reasons: the battery size update is only 10mAh, which hints at not much increase in processor power, nor screen size. However, it’s perfectly plausible Apple has managed to make a more efficient version of its chipset ahead of a flagship phone launch.

The antennas inside the motherboard are updated too, so once again signal performance should be enhanced… and really does make it seem likely that we’ll see some sort of 4G support.

The rear camera on the iPhone 5 is the same, but thinner 8 megapixel camera from the previous iPhone. It is a fine camera; however, some improvement would have been nice. The main enhancement to the camera comes in terms of software improvements, therefore they are also available on the iPhone 4S after an upgrade to iOS 6.

The new panorama feature lets you capture large sweeping vistas up to 240 degrees. This feature is super easy to use thanks to some intuitive software that allows you to take a momentous picture with one slow horizontal or vertical motion.

The iPhone’s connector has been replaced with a much smaller connector called lightning. The main advantage of the connector is its decreased size and reversibility, which means you do not have to think about which way you need to plug in the cable. The main downside of the new adaptor is that your current accessories and cables for your iPhone 4S or earlier (e.g. car kits and speakers) will not work with the new phone unless you buy an adaptor from Apple. This is an extra expense that may be frustrating for some.

The iPhone 5 sports the new custom designed A6 CPU, which offers app and graphics performance that is up to twice as fast as the previous A5. This should mean that the phone is smoother to navigate, apps load quicker and games look better.

The iPhone 5 also supports faster wireless performance via LTE. LTE stands for Long Term Evolution; however, to you and me it means 4G high speed internet on our mobile phones and other data devices.

LTE for the iPhone will initially be available in the UK from the operator EE (Everything Everywhere), who are a rebranded T-mobile and Orange. In the future three should offer support for LTE on the current iPhone 5; however, according to an article on engadget O2 and Vodafone will be not be able to support LTE on the current iPhone 5. This may change with future iPhone models.

A good change on the iPhone 5 comes in the area of accessories, as a new variety of earphones (EarPods ) are included . As you can guess, they fit better in your ear.

The rollout of LTE in the UK will start with major cities, such as London, Birmingham and Cardiff, so you many not initially be able to take advantage of the higher speeds. LTE is a good feature; however, the rollout will take time and you may need to initially swap networks to take advantage of it. As with 3G and Wi-Fi, if you find the feature is draining your battery it may be worthwhile switching it off if you are not taking advantage of it.
