Also, just send some $$ to Helmi who should be rewarded for his efforts.

You can change your Slot Cycle Index (SCI) from the default of 2 (which polls the tower every 5 seconds or so) to 1 or even 0. I have been running mine on SCI 0 for about 6 months now if someone calls my phone, it'll pick it up in less than 2 seconds (about 1 ring on the caller's phone) and start ringing. You can always tell you have an inbound call as the screen lights up about 200ms before it displays the Incoming call window. Your phone should now ring for about 10 seconds before going to voicemail.
To change it, you have to enter programming mode with your MSL and Lock Code. You can dial *2 and specifically ask for it (and even tell them what you're doing; they won't care/understand anyway). I did this hack in about 2 minutes before boarding a plane at Sea-Tac, fyi. It made a difference immediately.
Now, on HowardForums, I read up that the SCI set on your phone doesn't matter -- the tower has priority over the phone for this. So, the tower should allow you to receive calls quickly if it is configured properly and isn't under heavy load..otherwise it may adjust the settings overall to improve quality of service. Setting your phone to this setting may have no effect.
You'll have to report back on the effects if you decide to do this.
