Nokia Series 40

From Wikipedia, the free encyclopedia

Nokia 6610i

Nokia Series 40 is a platform for mobile phones based on the Nokia OS. It is found in more than 100 million devices^[1]. Series 40 devices all contain ARM processor cores driving a variety of RF technologies, such as GSM, UMTS and CDMA.

Series 40 uses a simpler operating system than the higher end Series 60, 80 and 90 (which are based on the multitasking Symbian OS). S40 devices differ from the Symbian-based platforms in that they do not support true multi-tasking and do not have a native code API for third parties and thus do not support installable applications other than MIDlets that are written in Java. It is primarily because of the former that Series 40 user interface appears to be more responsive and faster than other Nokia platforms, but much slower at running third party applications.

In the past, Series 40 devices have been restricted to smaller displays such as 128x128 pixels. With the latest third generation of Series 40, devices with resolutions as high as QVGA (240x320) are now available, such as the Nokia 5300.

[edit] Software

Standard applications include a XHTML browser and an e-mail client with POP3 and IMAP capabilities. The XHTML browser can access most web content through the service provider's XHTML/HTML gateway.

A major limitation in the phone software is that the e-mail client is not integrated with other applications; selecting an e-mail address from the phonebook or clicking on an e-mail link on a web page will not open the e-mail client. Instead a series of other communication methods is offered to contact the address, including SMS text message, MMS messages, all of which are charged a message-based fee by the service provider. Some models even have two e-mail applications; the real IP/GPRS based e-mail client, and an "e-mail" look-alike that tries to send e-mail as text messages through the service provider's SMS/SMTP gateway.

Support for SyncML synchronization with external services of the address book, calendar and notes is present. However with many S40 phones, these synchronization settings must be sent via an OTA text message. Manual editing of these settings are only possible for a limited set of details.
