Mobile Phones Batteries's nex in Apple iPhone

Mobile Phones Batteries Gadget fans will also hope that iPhone 2.0 makes much better use ofits built-in Bluetooth, which at the moment only works with a fewselected Apple-approved accessories. This could potentially allowiPhone owners to ‘pair' their handset with theirBluetooth-enabled computer to transfer files between them, andwirelessly connect to Bluetooth headphones and handsfree systems. Expect to see voice-dialling and speed-dialling added to iPhone 2.0as well - it seems ridiculous that such a cutting edge gadget ismissing so many of the utterly basic mobile phone functions andcapabilities that we've taken for granted on lesser handsets foryears. Apple could also add "proper" global positioning software to theiPhone, which would tie-in nicely with its Google Maps tool. At themoment, iPhones are able to triangulate a users' vague location bytriangulating their mobile phone signal with nearby masts andwireless internet hotspots. In truth, that's probably sufficientfor most iPhone users, and GPS is an expensive technology that isstill largely in its infancy on mobile phones. Adding it to theiPhone would probably increase the cost of the deviceprohibitively, and it's unlikely to improve navigation andtriangulation accuracy enough to justify the outlay. In terms of appearance, several industry analysts have said thatthey do not expect Apple to make any significant or dramaticchanges to the look of the device until early 2009. The maindifferences are likely to be that slightly convex back to make roomfor a 3G-capable battery, and a non-recessed headphone plug -plenty of iPhone users were left disgruntled to discover theirexpensive, noise canelling headphones didn't have a long enoughjack to fit into the current iPhone's sunken headphone socket. So, what won't we see with the new iPhone? Don't expect too manydramatic changes to its text-messaging functionality. Americans arenot big fans of "txting", and while we Brits would love to be ableto forward on text messages to other contacts in our address book,it's unlikely to be added to the device. Instead, keen texters willhave to look to the new Application Store for those sorts of tweaks- more of which below. It's also unlikely that Apple will make any dramatic changes to itstouchscreen keyboard. iPhone users have long hankered after theability to flip the iPhone for a horizontal keyboard layout, andhaptic feedback to indicate that buttons have been correctlypressed, but that sort of interface improvement is more likely toappear on the third-generation device rather than on iPhone 2.0. Opinions are divided on whether Apple will drop the 8GB version ofthe phone and instead offer 16GB and 32GB versions of the device,which would bring it into line with the storage capacity of theiPod touch range. The fact that Carphone Warehouse and O2 storesslashed the price of the 8GB model just a few weeks ago couldeither be taken as a sign that they were trying to clearsoon-to-be-discontinued stock, or that they are simply making a bitof extra space for the next-gen model. Personally, I think we will see an introduction of a 32GB model,not least because Apple will be making another big announcement atthe conference that is all about software, rather than hardware:details of the iPhone application store, that will allow people tobuy third-party programs and widgets through iTunes and installthem on their device. Essentially, Apple is seeking to make the hacking of iPhonesunecessary by providing a development ecosystem in which people canbuild small programs that improve, diversify and personalise theiPhone's capabilities. The iPhone is built on a stripped-downversion of Apple's OS X operate system, which means there is plentyof latent power that can be leveraged to turn the handset into amini computer of sorts. Expert to see some really clever bits of software that fill in thegaps Apple itself is not plugging, such as an instant-messagingprogram for the iPhone, nifty location-based features, such asrestaurant recommendations and movie reviews that tie into GoogleMaps and its triangulation capabilities, and even software to keeptrack of your company expenses. In many ways it is this, rather than the actual handset itself,that should dominate the headlines, because it is the platform,rather than the hardware, that is key to securing the enduringpopularity, flexibility and longevity of the device. But the poor old iPhone, rather like a handsome movie star, hasbeen typecast for its good looks and sex appeal. Still, there areworst things to build a reputation on.
