My new Volt has asked for permission to install "Sprint Connection Optimizer". What concerns are there (privacy, security) with this utility? I don't mind/care very much about the optimization of selecting WiFi vs. 4G and saving my WiFi password (the phone already does that and most of the time my life is binary - at home on WiFi or elsewhere on 3G/4G) but I do like the capability to read-write the SD card. I see it's easy to disable from the Settings menu. But once installed can I remove it - or is it like bloatware - difficult to get rid of? Does it affect my ability to root the phone? I'm on V4 and have read through the procedures to downgrade to V3, root, and then install the pre-rooted V4. If I do that will I need to reinstall this Sprint Connection Optimizer, or will it be unnecessary because rooting does everything this utility is supposed to do?
