Apple to unveil iPhone 3.0 OS update, new developer tools

Apple is expected to preview version 3.0 of its iPhone software this week.

Apple is expected to preview version 3.0 of its iPhone software this week, prompting speculation that a new iPhone may be in the works for summer release.

Next Tuesday, Apple will introduce the next version of the iPhone operating system, along with new tools for building iPhone applications downloaded from the company's App Store, according to an Apple invitation issued Thursday.

One thing to watch is how many of the changes take into account the needs of enterprise users and IT groups, where Apple has traditionally been weak.

The last major upgrade to the OS, version 2.0, was released in July, 2008, along with the new iPhone 3G.

A Dow Jones Newswire story quoted one Wall Street analyst, who envisions Apple offering a universal search capability -- letting a user easily sift through e-mail, contacts, and documents on the phone or on the Web, similar to a feature being touted by Palm for its upcoming Palm Pre phone.

But here are some other possible, and certainly hoped-for, changes:

"Tethering" which would let a laptop use a USB cable, Bluetooth or Wi-Fi to connect to the iPhone, and then use the phone's cellular radio to surf the Internet (you can do this yourself with a jail-broken iPhone.

Push e-mail notification.

Turn-by-turn directions.

Multimedia Messaging Service (MMS).

CNET's Tom Krazit thinks Apple may introduce what he calls true background processing -- the ability to run more than one application at once. That's something the Palm Pre and other platforms do offer.

Two interim OS releases have been made since last July. One was in November with version 2.2, which added support for Google Street Views, some user interface changes, and e-mail improvements, among other things.

Reviewers at the time complained it still lacked a range of features important to enterprise users  including on-device encryption, something better than four-digit numeric passwords, the ability to cut-and-paste, and synchronization of notes or setting up calendar items with Microsoft Exchange controls. Many of those are leftover complaints stemming from the enterprise shortcomings evident with version 2.0.

A minor OS update was released in January.

The new software development kit could presage an array of changes with the Apple development community.

It’s perfect for mobile workers. Just take it out — it’s small enough to sit anywhere — turn it on, load a sheet of paper, and start printing.

Wireless printing from my iPhone was also a handy feature, the whole experience was quick and seamless with no setup requirements - accessed through the default iOS printing menu options.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.
