Sharp GX30 has several major improvements on the GX20. One of the strengths of the GX20 was the VGA resolution camera. The Sharp GX30 goes one better with a 1.1 megapixel resolution camera - the highest resolution of any phone currently on the European market - with three and a half times the pixels of the old model. The screen, although the same large size as the GX20, has been upgraded to 262,000 colours. Instead of a tri-band phone, the Sharp GX30 is a quad-band phone. The GX20 didn't have Bluetooth - the GX30 does. In addition to all of this, the GX30 takes SD memory expansion cards and can play MP3s. The GX30 also has a much larger external display than the older phone |
