Well here is the deal. I had Sprint ADD the Esn of my Storm2 to thier database, well they tried at least, its a 3 day process, well it came back and said that "Device Vendor indicated device is not to be active on Sprint Network" So they tried but it didn't go thru.
Now I realize that Someone1234 you said you have had many 9530 and 9550 on Sprint, well the tough part is that maybe the 9530 with the old OS but the New 5.0 OS with its security doesn't allow you to get it into the service menu I am told. In your instructions you say: "Do the device swith, esn + pin and thats it". Sounds easy but please elaborate a bit, cause I have searched everywhere for this answer. What I gather from that statement is that you have another sprint branded BB device and you use the esn and pin from that bb and write it to the storm2. Then when you call to activate there should be no prob.
So after spending the last month on this I had Sprint attempt 3 times to load the esn into the system via Advanced tech support and each time was kicked back. Getting them to the point of adding an esn is tough enough as it is but whether or not it actually gets loaded is another question. So that leads me to believe the only way to have a Storm2 work on Sprint is by changing the esn + pin. So as of now my Storm2 has Sprint's PRL loaded on it and when I dial *2 it connects to sprint cust care, just the esn problem.
So Someone1234 please help out the many people in need of your knowledge here. PM if possible.
Peace
