The Sony Ericsson P1 is a smartphone and the successor of the P990. It was the last of the Sony Ericsson "P" Smartphone series, introduced in 2002 with the Sony Ericsson P800 and it integrates many of the hardware features of its predecessor the P990 in the form factor of the M600. It was announced on 8 May 2007. There is a Chinese version of P1 called P1c. Compare with P1/ P1i, P1c lacks of 3G, thereby using EDGE which is much slower but more available especially in the US and parts of Europe.
The phone uses the UIQ 3.0 software platform, which is based upon Symbian OS 9.1. It is slightly thicker than the M600 as a result of the new hardware features, but this is reportedly largely indiscernible. It is nonetheless considerably thinner than the P990 (25% smaller - as the official press review states).
As a result of its increased RAM, the P1's multitasking performance is more stable than that of the first batch of UIQ 3 phones from Sony Ericsson (P990, M600 and W950). The boot speed, when compared to the P990, is also discernibly faster.
