iMessage

iPad and iPod touch join the conversation.

With iMessage, we’ve created a new messaging service for all iOS 5 users. You can send unlimited text messages via Wi-Fi or 3G from your iPad, iPhone, or iPod touch to anyone with one of those devices. iMessage is built into the Messages app, so you can send text, photos, videos, locations, and contacts. Keep everyone in the loop with group messaging. Track your messages with delivery receipts and optional read receipts, see when someone’s typing, and enjoy secure encryption for text messages. Even start a conversation on one of your iOS devices and pick up where you left off on another.

Send more than text

Send photos, videos, contacts, or locations.

See when they’re typing

Ellipsis points appear when someone’s responding.

Newsstand

A custom newsstand for all your subscriptions.

Read all about it. All in one place. iOS 5 organizes your magazine and newspaper app subscriptions in Newsstand: a folder that lets you access your favorite publications quickly and easily. There’s also a new place on the App Store just for newspaper and magazine subscriptions. And you can get to it straight from Newsstand. New purchases go directly to your Newsstand folder. Then, as new issues become available, Newsstand automatically updates them in the background — complete with the latest covers. It’s kind of like having the paper delivered to your front door. Only better.

Reminders

A better way to do to-dos.

Next time you think to yourself, “Don’t forget to...,” just pull out your iPhone, iPad, or iPod touch and jot it down. Reminders lets you organize your life in to-do lists — complete with due dates and locations. Say you need to remember to pick up milk during your next grocery trip. Since Reminders can be location based, you’ll get an alert as soon as you pull into the supermarket parking lot. Reminders also works with iCal, Outlook, and iCloud, so changes you make update automatically on all your devices and calendars.

Camera

Capture the moment at a moment’s notice.

Since your iPhone is always with you, it’s often the best way to capture those unexpected moments. That’s why you’ll love the new camera features in iOS 5. You can open the Camera app right from the Lock screen. Use grid lines, pinch-to-zoom gestures, and single-tap focus and exposure locks to compose a picture on the fly. Then press the volume-up button to snap your photo in the nick of time. If you have Photo Stream enabled in iCloud, your photos automatically download to all your other devices.

Photos

Enhanced photo enhancements.

Turn your snapshots into frame-worthy photos in just a few taps. Crop, rotate, enhance, and remove red-eye without leaving the Photos app. Even organize your photos in albums — right on your device. With iCloud, you can push new photos to all your iOS devices. So if you’re taking photos on your iPhone, iCloud automatically sends copies to your iPad, where you can quickly touch them up before showing them off.

Safari

Even better site-seeing.

iOS 5 brings even more web-browsing features to iPhone, iPad, and iPod touch. Safari Reader displays web articles sans ads or clutter so you can read without distractions. Reading List lets you save interesting articles to peruse later, while iCloud keeps your list updated across all your devices. On iPad, tabbed browsing helps you keep track of multiple web pages and switch between them with ease. And iOS 5 improves Safari performance on all your iOS devices.

And back up and restore your device automatically using iCloud.

iOS is the world’s most popular gaming platform. With iOS 5, you can get your game face on with even more Game Center features. Post a profile picture. Meet your match with new friend recommendations based on the games you play and the players you already know. Discover new games without leaving Game Center. And size up an opponent on the spot with new overall achievement scores.1

Wi-Fi Sync
Wirelessly sync your iOS device to your Mac or PC over a shared Wi-Fi connection. Every time you connect your iOS device to a power source (say, overnight for charging), it automatically syncs and backs up any new content to iTunes.

Multitasking Gestures for iPad 2
iOS 5 includes a few new moves and shortcuts to help you get around even quicker on your iPad 2: Using four or five fingers, swipe up to reveal the multitasking bar, pinch to return to the Home screen, and swipe left or right to switch between apps.

AirPlay Mirroring
Wow your audience in the board room, classroom, or living room. AirPlay now supports video mirroring. Which means you can wirelessly — and securely — stream whatever’s on your iPad 2 or iPhone 4S to your HDTV via Apple TV. Everyone in the room sees exactly what’s on your iPad or iPhone display up on the big screen — even when you rotate your device from portrait to landscape or zoom in and out.2

Obscure Disease of the Day: Amebiasis (and how to avoid it)

Entamoeba histolytica trophozoites with ingested red cells
Amebiasis is a parasitic infection most commonly caused by Entamoeba histolytica. The parasite may cause both intestinal and extra-intestinal disease. Intestinal disease manifests as fever, chills, bloody or mucoid diarrhea, abdominal discomfort, or alternating diarrhea with constipation. Amebiasis is ubiquitous and typically transmits by the fecal-oral route. Here are steps to help avoid getting this infection.

 Steps

  1. Strengthen your immune system.
    Strengthen your immune system.
    Strengthen your immune system. Your first defence is your immune system and keeping it in excellent shape will help to prevent an infection from Entameoba histolytica:[1]
    • Drink enough pure water per day to keep you properly hydrated.
    • Eat plenty of fiber from fresh fruit, vegetables, and grains.
    • Don't dilute your stomach acid – it destroys most bugs. Avoid using antacids and baking soda (neat) where possible and don't drink liquid right before, during, or after a meal.
    • Take vitamins if you're not getting sufficient amounts from your food. Nourish the digestive system with a daily multivitamin, plenty of zinc and vitamin A.
  2. Take care when travelling.
    Take care when travelling.
    Take care when travelling. In the USA, a study in the early 2000s showed that over 50 percent of people infected by parasites had picked them up during their travels.[2] Be very careful about where you source your food and water from and reassure yourself of its cleanliness. Also be careful about where you swim.
  3. Practice good hygiene.
    Practice good hygiene.
    Practice good hygiene. Good hygiene is a key way to prevent contacting amebiasis, whether you're at home or travelling:
    • Always wash your hands with soap and warm running water for at least 10 seconds after defecation and after changing baby diapers.
    • Always wash your hands with soap and warm running water before preparing or eating food. Also scrub your fingernails prior to food preparation.[3]
    • Clean toilet seats before using, especially in public bathrooms. Use alcohol wipes or commercial toilet wipes made for the purpose.
  4. Take care with water sources.
    Take care with water sources.
    Take care with water sources. Do not drink untreated water contaminated by feces. Boil water of undetermined quality prior to drinking, or use bottled water if you cannot be sure of the water's quality, especially when travelling.
  5. Be aware of and implement safe food handling and eating practices.
    Be aware of and implement safe food handling and eating practices.
    Be aware of and implement safe food handling and eating practices. Avoid eating unpeeled or uncooked fruits or vegetables of questionable quality. Wash fruits and vegetables thoroughly, peel fruits, and boil vegetables prior to eating.
    • Boiling food above 50ºC or 122ºF will kill E. histolytica cysts.
    • Keep fruits and vegetables dry during storage. E. histolytica cysts are killed by desiccation.
    • Avoid dining at public places that appear unclean or that have questionable sanitary practices. Do not share sauces in one container with others in a party.
    • Be careful of salad bars, as salads can harbor the parasite.
  6. Control flies.
    Control flies.
    Control flies. Flies can carry the parasites. Protect foods against fly contamination by shielding them with a cover.
  7. Keep toileting activities way from the rest of the campsite
    Dispose of all human feces in a sanitary manner. If you have a garden near a septic tank, ensure that the tank is fully contained, not leaking, and is regularly emptied by trained personnel. If you're camping, keep all human waste activities well away from cooking and sleeping areas.



  Tips

  • Educate others, especially known carriers, about the importance of personal hygiene to prevent transmission.
  • Those working at childcare centres and hospitals have an increased risk of coming into contact with parasites.
  • Washing hands in cold water is better than not washing them at all.


Warnings

  • Do not use disinfectants dips for fruits and vegetables: they have unproved value in preventing amebiasis and might harm you.
  • Use of chemoprophylactic agents is ill-advised.


Things You'll Need

  • Soap and warm water
  • Bottled water (optional)
  • Clarity as to sanitary standards of dining out facilities
