FYI, the slot cycle defines how often the device wakes up and checks the CDMA network for messages, incoming calls, etc. This does not effect the throughput of a data connection. It will only improve responsiveness for catching incoming calls and messages from the network. Each increment in settings doubles or haves the interval time. Slot cycle 0 wakes the device to check the paging channel every 1.28s. 1 is every 2.56, 2 is 5.12s, etc. Only thing you are doing is using more battery....any other observations are a placebo.
