S60 devices
S60 is a feature rich software platform for smart phones with advanced data capabilities. These devices allow focused consumer-device segmentation in areas such as enterprise, entertainment, personal productivity, and games.
Devices based on the S60 platform feature:
Advanced telephony
Personal information manager (PIM) applications (such as Contacts list and Calendar)
Messaging
Internet browsing
Digital camera
Several S60 devices also provide features, such as media gallery, music player, FM radio, and video and sound recorders.
The following figure presents an example Series 60 device:
Display
The minimum requirements for a S60 device display are 176 x 208 pixel resolution (square-shaped pixels) and 256 color display (4096 colors preferred). S60 UI software is scalable from portrait to landscape display mode, in which the height and width of the display are switched. In landscape mode, some UI elements such as softkeys may change places. MIDlets designed for a certain resolution can be scaled to other resolutions supported by the mobile device.
Supported resolutions are:
176 x 208
208 x 176
240 x 320 (QVGA)
320 x 240 (QVGA)
352 x 416
416 x 352
For more information, see section Scalability.
Input
The following figure points out the required input keys on an example device.
The required input keys are:
Two softkeys (SK1 - left and SK2 - right)
Five-way navigation (four arrows and a Selection key)
Call creation and termination keys (Send and End keys)

Memory
The Nokia S60 devices use dynamic memory allocation, which allows the reuse of memory space once reserved and released. The shared heap size can be up to 20MB.
Many S60 devices support unlimited JAR size. For detailed information about each device, see the Device Specification section on Forum Nokia.
Note: There might also be device-specific maximum download sizes, which define the maximum size of content allowed to be downloaded to the device. In many products the maximum download size (for any content) is smaller than the maximum allowed application size. This means that it may be possible to install applications via PC suite, for example, where they could not be downloaded over the air.
