Found weird code in registry

[adewey234]

I was lookin through the registry in my HTC ROM and i found a weird key that said like engineering mode and it had a set of keys that i pressed. It is *#*#364#*#* and then it goes into like a program called GSM test mode. It has a lot of random info, and i was wondering if anyone knew what this was for

It just gives you some debug info on GSM/GPRS for the cell site you are connected to. Nothing useful unless you work for a telecom company and are doing cell site testing, or work for for HTC :)
