Sony Ericsson P900
Like other Symbian-based smartphones, the P900 is an open phone, which means that it is possible to develop and install third party applications without restrictions. A UIQ 2.1 SDK based upon Symbian C++ is freely available from the Sony Ericsson developer website . Additionally, the P900 supports applications written in Java.
Because of this openness, a great number of third-party applications exist that can be used on the P900 and other UIQ phones (such as the Motorola A1000 and BenQ P30). Many are shareware and freeware.
As the P900 uses UIQ version 2.1 it is backwards compatible with UIQ 2.0 as found in the P800. Applications made for the P800 will normally work on a P900 as well. It, like the P800 and P910i, has an ARM9 processor clocked at 156MHz.
The P900 can be used without the flip as well, acting more like a PDA, but still usable as a phone. The P900 supports Memory Stick Duo cards (but not Memory Stick Pro Duo) up to 128MB in size, as does the P800. However, it has been confirmed that this 128MB limit is just a software restriction.
An updated version of the P900, the Sony Ericsson P910i was released in July 2004. It features a small QWERTY keyboard and enhanced software, but was reported to be less battery-efficient. The P910i has double the P900's memory (64 MB, versus the P900's 32 MB) and supports Memory Stick Pro Duo, allowing the phone up to 4 GB of storage on a single card.
Some of the specifications of the P900 are:
- Triband GSM - 900 / 1800 / 1900 MHz
- Dimensions - 115 x 57 x 24 mm
- Weight - 150 g (with flip), 140 g (without flip)
- Internal camera: VGA (Display resolution up to 640 x 480 pixels)
- Connectivity: Bluetooth, Infrared, USB dock
- GPRS (WAP 2.0)
- Messaging: SMS, EMS, MMS, POP3, IMAP, SMTP
- The P900 has a software restriction on the size of the memory card that can be used (128 MB).
- The P900 software does not support HTML email.
- The P900 software does not provide an option to alter the screen brightness.
- Flashing the firmware is cheaper than purchasing a new P910.
Though this may seem all beneficial, there may be the drawback of not being able to connect to certain Bluetooth headsets (however, this is rare).
Though the P905 may be identical to the P910 in software terms they are not identical in hardware terms.
