We are developing a system for a company in mainland china. We were planning on using iPAQ H5550 with a expansion pack where we would slip in a Sierra Wireless 555R aircard. Also using a Socket SDIO scanner. The H5550 was perfect. Now we learn that HP isn't making the H5550 anymore. Plus to make matters worse, the replacment iPAQ won't have an expansion packs!. So we have no PC card slot for the aircard. HP is hopeless when it comes to customer support so we are dead in the water. Anyone have any ideas?
