I've actually looked into this....and it can be 2 things...atleast that i know of. The signal wake is one of them, but the other one is due to the Time Syncronization with the sprint network...theres a setting within the phone that automatically sync's your phone time with the network witch in turn will wake your device. I went in and manually disabled the auto sync and my screen didn't come back on.

Figured I would throw that out there to see if anyone might want it. Theres also the lock option on 6.5 that people can use, it has the slider to unlock.
