My desire is currently an orange branded handset. I'm going to be rooting fairly soon, but want to make sure on something first. Several people have said they have rooted orange branded handsets and installed custom Roms. Is there any way to know if a Rom will work before trying it? Plus how do you know that the Rom and radio version will not simlock the phone or knacker the WiFi? Do I just have to read the instructions very carefully on each Rom? Or is there another way?
