My iPhone 4s is on its last leg. It's been dropped to many times. So I'm looking at picking up a s3. For vzw network so the people that own one can u chime in. On the battery life, how smooth is the new update jelly bean(project butter), how's the quality of the apps, how's the Bluetooth/wifi/gps signal,how's the speaker and internal speaker,also anyone notice any lagging at all on the device. Thanks guys 😃
