I heard rumors that the phone would automatically pull down and install any updates on its first power-on. At the Sprint store, I was afraid the techs there would install the update even if it asked. Being concerned, I took the phone home to activate it myself. Anyway, I just got home and my phone is still boxed up. Surely by now others have gotten their phones and turned them on. So, is it safe to turn it on and use it? Will I get the chance to not install the update even if this is the first time it's powered on?
