I'm currently running att s2 on straight talk SIM and have had many issues but I'm not sure enough to switch BACK to virgin. I switched from virgin for a better phone. I always check every one in a while to see what androids they put on and the evo looks pretty good but I do have some questions I hope someone can answer.... what's the ram and internal memory of this phone? Don't think I saw that in the vm site. How's the audio and sound quality? The volume of phone conversation is what I'm really referring to. But music audio and ringtone are important to me too. Also can this phone still access data while on a phone call? Battery life? I know smart phone s are likely to drain faster Battery
