It looks just like any other usb cable to be truthful, connnectors are identically the same (though it is a bit more stiff than the original Q's usb cable). There really isn't a way to know you've got one that came from a Blackberry unless you find someone who already has a blackberry 7510 (nextel model) which is the type I used. The only reason I stated this very specific model is because it's the only thing that worked for me and if it worked for me SEVEN TIMES to get out of the boot rom flash screen when everyone else was telling me it couldn't be fixed (Motorola, Sprint, all other forums) other than sending it in for repair; then it would only be helpful to you & others if I stated EXACTLYwhat it was that enabled me to correct the problem. You may find another usb cable from somewhere else that works - who knows. I'm just telling you if you want to be 100% on what I did to fix it, find someone with a blackberry 7510 (old blue & bulky nextel iDEN phone) and use that cable (a store perhaps? They may look at you weird, but bring a laptop with the motorola update software & activesync on it to do it on the spot).
