I currently have a 3 year old Samsung Eternity (technically, it's not even a smartphone), but, after reading some of the recent threads here, I'm curious if I'll be losing features when I upgrade to an iPhone 5. Sound profiles? Right now, with 2 clicks, I can set it to one of 4 customizable profiles (Normal, Silent, Driving, and Outdoor)... each with separate settings for ringtones and message alerts. Ideally, I'd love the ability to fully customize settings down to the caller (or group of callers). For instance, a customized profile called 'emergencies' which would silence everything except for the 'family' group... and so on, without having to change every contact manually every time. Another feature my phone has that I love is the ability to 'auto-reject' calls from certain numbers. If any number from the list calls, it will send them straight to voice mail without ringing and interrupting me.... a great feature when dealing with harassing phone calls, telemarketers, or even work when I'm on vacation.
