Iphone OS 3.0 Beta

March 18th, 2009

iPhone 3G

I’m totally excited. Yesterday Apple announced the newest version of the iPhone OS, 3.0, to be available in June 2009 to both iPhones (original and 3G), and iPod Touch (1st and 2nd generation).  For those building iPhone apps, the beta version of 3.0 SDK is available now.  That means developers can actually start playing with 3.0 TODAY.

Here’s my favs from what’s new in 3.0

  • Cut, Copy, and Paste (finally)
  • Send photos, contacts, audio files, and location via MMS (iPhone 3G only)
  • Push Notification Service
  • In App Purchase Support
  • Peer to Peer Support
  • Maps API
  • Audio and Video Enhancements

I’m glad to see cut’n’paste is gonna finally work.  So many times I want to copy a URL from a text or email to Safari, or copy an address to google maps.  However, I’m really pissed that MMS (send a picture message) is only for iPhone 3G.  Back in 2005 I was using my cell phone to send pictures AND VIDEO to my friends phones.  2 years later I bought the iPhone, and now I still can’t do it.  As a phone, iPhone kinda sux.  But as the most awesome portable touchscreen internet customizable high quality audio and video playback device, iPhone rules.

I like the “Push Notification Service” because it allows custom iPhone apps to do receive messages from the internet even if they are not running.  For example, when you get a SMS Text message, an alert pops up on the iPhone with the text message, which you can close or reply, launching the Text Messaging app.  Similarly, the new push service allows an alert to pop up for a custom app.   However, if user hits close the alert goes away and the app is not run.   That means that background processing is still not allowed.  Another way to view it is:  Internet –>  iphone –> Human –> iphone app.  I much prefer this view:  Internet –>  iphone –> iphone app.  Skip that human interactive component and let the app process a notification as it sees fit.   NOTE: originally I thought 3.0 would allow background processing, but 3.0 beta SDK corrected me.

If you want to make money, the “In App Purchase Support” is huge.  You can make an app cost $0.99 in iTunes, offering some basic functionality at a low price point for mass adoption.  Then offer premium services for an additional $1.99 (or whatever) right there in the app – it does not get easier.  Perfect for games (download the next 10 levels for $1.99) or for monthly services ($5.99 for next months premium financial or sports information).

Peer to Peer Support is cool because it makes it easier for iPhones to talk to each other (or other devices that support apple’s bonjour protocol).  Examples include games (just like online multiplayer playstation games), exchanging virtual business cards, or sharing documents.

Maps API has a lot of potential, especially since its closely intergrated with Google Maps API (terms).  Combined with location aware (GPS or cell tower triangulation) phones, this makes it much easier for apps to have custom annotations displayed near the user’s location.  You can also do some of this in safari, skipping the iPhone app and just makeing a website page specific for iPhones (the new safari in 3.0 allows javascript to know users location).

Audio and Video have also been updated.  With iPod Library Access, an app can play any song on the phone. One example would be a game tied to a specific playlist, where each game event (begin, score, foul, goodbye) is mapped to a song, allowing users to customize the audio themselves.  Video Streaming is improved – now you can playback video streamed from a standard HTTP (Web) Server.  Expect more websites to have a feed made for mobile devices. Core Audio and Audio Recording got newer engines under the hood, including support for more codecs and software decoding.
