NO. And I am glad they told the OP so as well. We had the problem of MetroPCS saying they could 'flash' the razr (V3c/m) to Metro for about $40, when all they did was add and activate the ESN to their database, so for the readers,
look out. All that did was enable calls and sms, but anything data would not work. So then when the user actually flashed MetroPCS firmware (sorry not this easy for the A855) on their phone, it was another $40!
And to the OP, as stated the process is hard, but doable. I don't know why the link previously posted is gone, maybe it's a DF thing, but I will post the main one I know of:
service programming on the moto droid
I believe you can shortcut through the history and stuff and jump to the last three pages, but sometimes it's best to read more just to get a whole handle on it. And some of it is shortcutted (is that a word?) here:

good luck
