The P1i is Sony Ericsson’s new flagship smartphone product. Running the touchscreen variant of UIQ 3.0 on Symbian OS 9.1, with WCDMA, GSM and Wi-Fi connectivity, a QWERTY keyboard or handwriting recognition for text input and a 3.2 megapixel camera, it is well specified and a powerful smartphone.
The P1i uses the same UIQ 3 software platform as the P990 and there are relatively few software differences between the two phones. However, the P1i has double the RAM of the P990 and this has important implications for software operation and stability which we will discuss more fully in the second part of this review. In this first part of the review we concentrate on the hardware which has also had a very significant overhaul.
