So I got the Virgin mobile HTC evo v for Christmas last year and the phone had GREATLY downgraded (Mediocre battery, lasts from about 7AM to 4 PM). I wanted the iPhone 4 last year for Christmas but decided to get the evo. Now Christmas is coming again (I upgrade every Christmas) and now that virgin has LTE, I'm tempted to get the optimus F3. I've heard great battery life reviews about it. However I've only used iOS on my iPod touch 4G. So the question is iPhone 4 or optimus F3?
