same update works for both boxes..hd 2244IR and hd 2244 RF..cc wont be able to confirm this but u can confirm it from your d2h engg..they are just giving away hd 2244 infrared remote box as sd bcoz they launched RF remote boxes. when i login to my d2h account it shows digistb 1111 n box even though i am using hd2244 IR..its just they activate the IR box as sd and RF box as HD..
