I am a realtor. I open Lock Boxes on homesin my area with the IR port on my ppc6700 from sprint using software call supra e key. I have had my 6700 for about 3 years and its starting to get worne out. I would love to upgrade to a phone like the HTC touch diamond but I dont think it has a IR port and im not sure the supra e key software will run on the touch its a windows program. Dose anyone know if you can get some type of external IR port that you could plug into the data port on the touch. or dose someone know of a top of the line phone that has a IR port on it from Sprint.
