The camera onboard the Samsung C5510 has 2 megapixel resolution and sadly no autofocus. Bluetooth v2.1, USB v2.0 and a microSD card slot with support for up to 16GB memory cards complete the specs list.

Moving on to Samsung M2510 we see quad-band GSM support and a 2.2" TFT QCIF display. The 3G support has been sacrificed in order to bring the price down, but all music-related features seem intact.
