Iphone 4 Features

By

The iPhone 4 is a dramatic redesign. It manages to pack a radically sharper screen; a second, front-facing camera; a larger battery; a better rear camera with flash; and a faster processor into a body that is 24% thinner, a bit narrower, and retains the same length and weight as its predecessor's. In fact, Apple claims that the iPhone 4 is the world's thinnest smartphone and sports the world's highest-resolution smartphone screen.With the front-facing camera, and clever new software called FaceTime, Apple has brought simple, high-quality video calling to mobile phones, albeit, for now, only over Wi-Fi and only among iPhone 4 owners. In multiple tests, this feature worked very well for me and is a classic example of the value of having one company do integrated hardware and software.

In addition, the iPhone now includes an updated operating system—which also can be installed free on the prior model—that introduces catch-up software features such as limited multitasking (the ability to run apps simultaneously); folders for grouping related apps; and, for email, a unified inbox for multiple accounts and the ability to present messages as threaded conversations. This software is called iOS4.

The iPhone 4 will cost the same as the iPhone 3GS: $199 for a model with 16 gigabytes of memory and $299 for 32 gigabytes, with a two-year contract from AT&T. The 3GS model will drop to $99 with a two-year contract and 8 gigabytes of memory.Physically, the iPhone 4 is attractive and feels great in the hand. Even the back is now clad in glass, which Apple claims is a superstrong variety 30 times tougher than plastic. I dropped it several times from a few feet onto a hard surface with no problem, and it acquired no scratches at all in my testing, even though I didn't use a case or coddle it.

Although it is the same weight as its predecessor, the iPhone 4 feels denser and tighter—more like a fine possession than a disposable gadget. It still looks like an iPhone, but it manages to make the 3GS While its 3.5-inch screen, once considered huge, is now smaller than those on some other smartphones, the high resolution packs in a lot of material and makes text appear almost like ink on fine paper. The software is simply richer looking and smoother to use than on competing phones I've tested, with fewer confusing menus and settings, and far more apps.

How to turn off Ringbacks on Rogers

By
Rogers just update you to the latest iPhone value pack, or figure out some other way to stick you with their ringbacks service, and you’re desperate to find out how to turn it off? They don’t want to make it easy — they want you to pay money for more Ringbacks — but after over an hour of waiting on 3 different customer service and tech support reps, I got the answer. Here it is: From your Rogers iPhone, text 555 with the word OFF. You’ll get an autoreponder with a link to http://rogers.com/ringbacksoff Tap the link. You need to be on Rogers’ network (i.e. not Wi-Fi) to access this page! Scroll down to the bottom and turn OFF both Ringbacks and Voice Greetings. (Yes, Ringbacks are so annoying they require and additionally annoying Voice Greeting to beg the people who call you not to hang up while they’re annoyed by the Ringback.) Rogers tried to get me to give Ringbacks a chance, saying if I loved the Beatles and my friends new I loved the Beatles, I could entertain them w...

Best Ipad and Iphone Photography Apps

By
Longtime Exposure Calculator Price: Free/ Available for iPhone, iPod touch, iPad Long-exposure photography fanatics will know that an ND filter can be essential when it comes to extending exposure time for those all-important open shutter shots. Longtime Exposure Calculator by HPR-Solutions is a free iPhone,iPad and iPod touch app that enables you to dial in a projected shutter speed to one column and then 'add' an ND filter as graded in both f/stops and filter names (eg 3 stop or ND8) in the other column. The app then calculates the adjusted exposure. While it is, in part, possible to TTL meter with an ND filter attached to the front of a camera's lens, the results won't always be accurate, and there's a point where things get so dark that it's not possible - especially with in-vogue super-dense filters. Having an off-camera calculation method such as this makes it quick and easy to figure out exposures without so much as needing to put those brain...

How to Reload Operating System on Nuked or Bricked BlackBerry

By
Good Afternoon Class! I’ve been a bit slack in my  BlackBerry 101  lectures as of late – I blame the  Smartphone Round Robin , all the  Contests  we’ve been running on the site and the busy Holiday Season. My apologies! This will be the last 101 lecture of the year… but we’ll be back in 2008 bigger and better than ever. Today’s lecture isn’t really a “newbie” topic, but it’s one that I wanted to cover because in the past three weeks I’ve gone through it half a dozen times and that is  Reloading the Operating System on a BlackBerry that’s totally “Nuked” . I’m not sure if nuked is the technically appropriate word for it (I also use one that starts with an F and ends in an ED and has a CK in the middle), but it is how I refer to a BlackBerry that is stuck in a permanent reboot cycle and is completely, completely unusable. With a Nuked Berry, essentially the device turns on (red LED comes on for a few seconds), then you see the white screen with the hou...
