Ultimate Mobile OS Showdown: iPhone vs Android vs webOs vs Blackberry vs Windows Mobile vs Symbian
Symbian OS Fifth Edition
Nokia phones, like the BlackBerry, are amazingly popular all over the world – the company sold about 113 million handsets in 2008, or about one third of all cell phone sales worldwide. This makes the Symbian S60 OS the most widely used smartphone platform in the world. The one caveat here is that the latest touch-enabled version, called Fifth Edition, runs on only two models: the N97 and the 5800.
The N97 is the more powerful of the two, at least in terms of extra features. The phone uses an ARM 11 processor running at 434 MHz, has a 5 megapixel camera, and has a large 3.5-inch, 16:9 widescreen display running at 360 x 640, the largest of the phones we tested. The Symbian S60 OS is the latest iteration of a smartphone operating system that has been around for ages – some still swear by it, and there is a long history of unusual apps for, say, controlling home automation devices. The OS is hampered on the N97 somewhat by one of the slower processors for a modern smartphone.
App Speed Test
App speed is near instant for the most common apps, such as Contacts and Messaging. Predictably, the camera app took about six seconds to load, which was slower than any other smartphone OSes we tested. We also found the Ovi app store was slow and touchy when we wanted to search for games and utilities. Nokia puts all of the apps, media files, and customization options in the Ovi store and it can be unwieldy to use and switch from one category to another too easily. Overall, S60 is a fast OS even on a slow processor – apps tend to look more like BlackBerry OS with thin lines and text without the graphical touches of the Palm Pre and iPhone, which makes the OS run fast but not look as good.

The Facebook app shows a truncated view on the main screen and the full app loaded quickly.

Ovi – the new app store for Symbian – loaded slower than any other app store in our tests.
App Availability
Nokia does not release the total number of apps available in the Ovi app store, because the number varies by device. The N97 comes bundled with a wide selection of apps. There is the typical contact manager, calendar, maps utility, and browser. And, there’s a tool for notes, a clock, and a voice recorder. The surprise is that there are quite a few extra apps included. There’s a PDF reader, a currency converter, and the QuickOffice suite for reading docs, spreadsheets, and slideshows. In a testament to the prowess of the older, more mature OS, there’s even a compression utility for opening Zip files, a podcast search app, an FM radio client, and a handful of included games. (Our N97 came with Spore and Brain Challenge pre-loaded.) Suffice it to say, S60 lacks the vast number of innovative third-party apps that are available on the iPhone and Android OS. Try as we might, we couldn’t find even basic apps such as a Pandora client, a Last.fm player, or a YouTube client. There was even a limited selection of Twitter apps, including a couple (such as KiTwitts) that crashed way too often. Overall, S60 Fifth Edition is not the OS for people who want to load up their Nokia phone with extra apps.

The old stand-by, Accuweather is available for Symbian S60 Fifth Edition.

Symbian can't touch the iPhone for games, but there are a few good ones – such as BrainChellenge.
Multi-tasking Support
Multi-tasking support is phenomenal on the S60. In our tests, we found we could open about six or eight apps at once without any problems, even though the phone only has 128MB of memory. We also found that, when we opened a game such as Brain Challenge, and switched away from the app, when we returned to it, the game was in the exact same point when we switched.

You can select from a menu of open apps to multi-task between them.
Media Support
Symbian S60 Fifth Edition supports a vast number of audio formats – exactly 22 in fact, including WAV, RealAudio, MP3, and just about anything you can imagine and then a few more. The OS also supports RealVideo, WMV, H.263 and H.264, MPEG-4, and Flash Video. And, for photo formats, the OS reads BMP, EXIF, GIF87a, GIF89a, JPEG, JPEG 2000, MBM, OTA, PNG, TIFF, WBMP, WMF. In other words, S60 crushes the competition for multi-media support and crosses geographic boundaries in terms of what is popular in the US, UK, and other countries.
Organizational Tools
We prefer the Palm Pre's webOS contact management system to the Symbian’s, which are relatively basic. Palm, Apple, and Android also all do a better job of syncing your calendar and contacts with Web apps such as Gmail and MobileMe. There is a notes app, and a Microsoft Office file reader called QuickOffice. Symbian S60 also includes a PDF Reader.

There is not much space for contacts list, and Symbian lacks the advanced features of BlackBerry OS.

The textual interface for the calendar looks more like the one in BlackBerry OS than an iPhone.
PC and Database Sync
Symbian OS seems to be in a bit of a quandary when it comes to sync and desktop support. Nokia includes several apps to help you sync up media files, but they do not work with iTunes, which is a plus for the Palm Pre and the iPhone OS column. The iPhone OS also has a leg-up with a few full-featured apps that sync to a remote database, such as Daylite Sync and Qlikview.
Messaging
Symbian S60 Fifth edition shows your current messages right on the home screen, using a widget-like interface that's highly accessible but also a little crowded, even on the Nokia N97's widescreen display. It's easy to add Webmail accounts to the Messaging app, but Symbian can't keep pace with how Palm's webOS adds multiple accounts to the same inbox, or how Apple iPhone syncs messages so easily and intuitively with their MobileMe service. Nokia needs their own messaging portal similar to what they accomplished with the Ovi appstore, although the OS does support Microsoft Exchange.

Symbian OS supports Microsoft Exchange, your own ISP, and Webmail accounts like Gmail.
Flash Support
The S60 operating system was the only smartphone OS that even made an attempt to support Flash. Even though it is Flash Lite 3.0, and it is getting quite old, at least the phone does support animated images. We tested the GideonMobile.com site for Flash and it worked smoothly. For regular Flash support, S60 is just as limited as the other operating systems we tested.

Symbian S60 supports Flash Lite, the older mobile standard, but not standard Flash.
Network Support
Our Nokia N97 supported 802.11g wireless, and we used a T-Mobile SIM card to access an HSDPA network at 1 Mbps. The OS also supports Bluetooth Stereo.
Conclusion
We were hesitant to put Symbian OS near the bottom of the list. After all, it is a powerful OS with a long history, and millions use it. The main problem we had, other than not finding too many apps in the Ovi store, is that the OS just doesn't do anything better than the top pick, in just about any category. Apple's iPhone OS has more apps, BlackBerry OS runs faster, and Palm's webOS is easier to use.
