Don't know if this is normal performance or a problem. Any thoughts appreciated. I'm in LA where 3G coverage is nearly everywhere. I've noticed that my phone when outdoors in unobstructed areas will be operating in 1x mode where I'm certain there is 3G, in fact there was 3G on other days. I'll watch it for 5 minutes thinking it might switch to 3G but it doesn't. I power down to reboot phone and invariably it comes up 3G. Do I have a phone problem ? It's like it gets stuck on 1x in a weak area and stays there until reboot.
