T-Mobile U.S.A. is no longer offering the iPAQ h6315 cellular-wireless Pocket PC. This was the only carrier in the United States offering this device.
T-Mobile began selling the h6315 in August of last year. Since that time the device has not done terribly well, which could explain why it was dropped after only seven months on the market.
In February, HP released a ROM update that fixed many bugs in some h6300 series models, but one has not yet appeared for the T-Mobile U.S.A. version.
This iPAQ is no longer listed on the T-Mobile web site, and it has reportedly been pulled from all stores.
Recently, HP announced the iPAQ hw6500, a cellular-wireless Pocket PC expected to debut in the second half of April.
It will not include one important feature its predecessor has: Wi-Fi. However, it will support EDGE, which means its average data transfer speed is around 135 kilobits per second (kbps), noticeably faster than regular GSM/GPRS networks.
HP has not revealed which carriers will be offering the hw6500, but Cingular is almost certainly amoung them. This is the only U.S. company with a significant EDGE wireless network.
Thanks to Dingo for the tip.
