Here's a sweet exploit I came up with while waiting in line at the Sprint PCS store. First a little back story, Sprint PCS is a digital CDMA network making it virtually impossible to clone...or so we thought. The weakness of Sprint's network is that there digital coverage is pathetic. To fill up the HUGE holes in their network, Sprint has roaming agreements throughout the US. The roaming agreement is that whenever there isn't a digital signal (1900) the phones will drop to analog (800) which is what Sprint calls "roaming".

THE EXPLOIT

Every Sprint PCS store has a sales floor where they have activated phones that you can pick up and use. Sprint stores do that so you can try out their phones to hear the sound quality of each different phone before you buy one or to call home(or anyone) as a courtesy call. In fact, every time I go to a Sprint store I always make at least 15-20 prank calls all over the US.

Basically all you need to do is:

1. Go through the menu and look for the phone's telephone number which is your MIN (mobile id number)
2. Look at the back of the phone and find an 8 character number/letter sequence and this is your ESN.
3. Program the ESN and MIN into your analog OKI-900 phone.

Guess what you just cloned the Sprint PCS's courtesy phone. So when you use your cloned OKI-900 phone, Sprint PCS will think your roaming since your using an analog only phone.

These phones are activated using unlimited calling minutes and I doubt that the Sprint PCS store looks though the hundreds off phones calls that are made from these phones each month so there's little to no chance of getting caught. There's like 7-8 different models out right now so you should get all 7-8 accounts and use'em like crazy.
