Has anyone been able to adjust the amount of rings on their phone? My phone rings about 6 times before it goes to voicemail but my girlfriend's phone rings only 4 times. I brought both numbers over from T-Mobile where they each rang about 4 times but now w/Verizon mine went up to 6. Tried calling tech support about it and they said there wasn't a setting for this on the phone itself and they gave me an answer like some phones just tend to connect to the network faster . Any ideas??
