Ipad Vs Ipad 2 - what changed?

By

A lot of people are asking me for a rundown of the differences between the original iPad and the new iPad 2 unveiled yesterday. Here’s a quick rundown of what’s changed, and what hasn’t changed.
Dimensions - CHANGED (slightly)
While the overall footprint of the iPad 2 is the same as that of the iPad, the thickness has gone down from 13.4mm to 8.8mm. The weight is also down for all models (WiFi model down from 680g to 601g while the WiFi + 3G is down from 730g to 613g for the AT&T model and 607g for the Verizon model.
Screen - UNCHANGED
No change here - The iPad 2 makes use of the same 9.7-inch LED-backlit IPS 1024 x 768 screen as the original iPad. At this point one unknown relating to the screen is what graphics processor Apple has used. The original iPad used a PowerVR SGX 535 chip. We’ll have to wait for the teardowns to find this out.
Processor - UPDATED
Out with the old 1GHz single-core A4 chip, and in with a dual-core 1GHz A5 chip. The original A4 featured 256MB of RAM while the iPhone 4 has 512MB. Again, we’re going to have to wait for the teardowns to appear to know if this has changed.
Storage - UNCHNAGED
The options for storage remain the same - 16GB, 32GB and 64GB.
Radios - UPDATED
While WiFi and Bluetooth ramain the same (802.11 a/b/g/n and 2.1 + EDR respectively) the cell radio in the updated ipad has been updated. The original iPad featured EDGE plus triband HSPA while the iPad 2 features EDGE plus quadband UMTS/HSDPA/HSUPA (850, 900, 1900, 2100 MHz) and GSM/EDGE (850, 900, 1800, 1900 MHz) for the AT&T versions and CDMA EV-DO Rev. A (800, 1900 MHz) for the Verizon model.
Price - UNCHANGED
The price remains unchanged for all models - iPad 2 starts at $499 for the 16GB WiFi-only model.
New features
There are a few features completely new to the iPad 2. Here’s a rundown:
  • Front-facing VGA camera
  • Rear-facing 720p camera
  • Gyroscope
  • New case (optional) that is attached by magnets (how DO they work? ;) and features a microfibre surface.
  • HDMI output dongle (optional).

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...

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...

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...
