My iPod Touch slowed to a crawl, making the many useful new iPhone update features hard to use -- at first The hype over the new iPhone 3.0 OS has matched Apple’s previous frenzied heights. We’ve all been guilty of getting excited over a new version that added long-desired capabilities such as copy and paste and content searching, but now that the new OS is real (it became available yesterday), does it live up to our hopes and dreams?For the most part.I downloaded the new iPhone OS onto my first-generation iPod Touch, after paying the $10 upgrade fee. The installation was easy. And after about 10 minutes, when the new OS was installed and my iPod Touch was updated, I eagerly took my device out of its dock. And waited. And waited. It was excruciatingly slow, even for simple tasks such as switching from the home page to the setup app. Everything — mail, calendar, App Store, iTunes, you name it — simply lags for sometimes several seconds after you click the Home button or tap an option or swipe the screen. (And, yes, I even powered down to see if “rebooting” would clear the system. It didn’t.) I began to think that Apple had taken a page out of Microsoft’s book: Make sure a new OS at least neutralizes any faster hardware.My anguish was acute, especially because you can’t really reverse an OS upgrade on an iPhone. But over the course of a couple of hours, my iPod Touch got faster, getting close to its old speeds. (I strongly suspect the slowdown was caused by the Spotlight search feature indexing all the content on my device.) I don’t like the slight lag that still exists, but my fear that I was stuck with a mud machine has faded.As we installed the iPhone 3.0 OS on other users’ devices, it became clear that the slowdown I experienced was related to how much data I had on my iPod Touch (about 8GB of music, a calendar with two years’ of appointments, and two e-mail accounts, including an Exchange-based one with thousands of messages). Devices with little information had no slowdown, and after the initial Spotlight indexing was done, performance was at or near the old OS’ speed. Phewww! What business users will love Assuming that such slowdowns are short-lived for everyone else as well, does the iPhone OS 3.0 bring significant advantage to business users? Back in November 2008, I found that the iPhone OS 2.2 didn’t really overcome the limitations that frustrated me — some of which have been fixed in the iPhone OS 3.0.Let’s start with the big one: copy and paste. It’s easy. Double-tap on text and the nearest word is highlighted, and a menu with Select and Select All appears. If you choose Select, two drag bars appear, one on either side. Drag either bar to expand the selection. When done, click Cut or Copy in the menu above your selection. (Cut appears only if you can actually edit the content, such as in an e-mail you are writing, as opposed to one you are reading.) Go to any other app with content, and double-click where you want to paste the text or graphic, then click the Paste menu that appears. If you are in read-only text, no Paste menu appears. It works exactly as you would expect.For graphics and for protected text on the Web, copy and paste work a little differently: Tap and hold on the item you want to copy or cut, and it becomes highlighted. On a Web page, a paragraph or div may be highlighted. Tap Copy from the menu that appears. Some items open additional menus, such as Save Image or, for a hyperlinked item, Open in New Window. The iPhone OS makes the device act more like a computer in these basic content operations. The other big change is the inclusion of Spotlight, Apple’s search technology for on-device content. Its location is nonintuitive — you swipe to the left of the Home page to open the Spotlight page — but once you know where it is, it’s easy to get to and use. Enter your search term, and all content on your device that contains the search term is listed. Click an item and the appropriate app opens up with the content in question. Easy. And you can search your mail separately with the new search window when looking at your inbox or any folder in it — just be sure to scroll up past the top of the window to make it visible. There’s also a preference setting to determine exactly what is searched and what is not. If you use Exchange 2007, Spotlight can search the server’s folders as well.Many people wanted the iPhone OS to support Mail, Messaging, Notes, and Safari in landscape mode, which it now does. And the touch keyboard also works in landscape mode, making its buttons bigger and easier to press. It works perfectly well, but note that the landscape mode screen depth leaves little room for seeing what you are typing, so you may let more mistakes go unnoticed. Or you may make fewer mistakes in the first place.Mail and calendar capabilities are nicely, but not fully, improved. You can now respond to Exchange invitations from your device — and invite others — but only if you use Exchange. And you can specify which mail folders are automatically synchronized, no longer limited to the inbox (before, other folders were synced only when you opened them). The iPhone still cannot open .ics invitations that come from or into non-Exchange e-mail accounts. Sorry, but we don’t live in an Exchange-only world, so even if your workplace uses Exchange, many business colleagues will use something else. Technology Industry
