The P527 is an unlocked GSM Pocket PC phone that's sold in the US. It features an integrated SiRF III GPS, and is available with ASUS Go navigation software and maps of North America on a microSD card. The P527 isn't offered by a US carrier, but is sold by a few US retailers (mostly online). It's a quad band GSM Windows Mobile 6 Professional phone with EDGE for data and it has WiFi and Bluetooth 2.0 +EDR. It has a 2 megapixel camera with autofocus lens and a microSD card slot that supports SDHC high capacity card. The ASUS runs on a 200MHz TI processor with 64 megs of RAM, which means it's not the fastest kid on the block. The P527 is one of the few PPC phones with a hardware number pad and true candybar phone design.
