Yesterday, all day, I had no signal at all...just an x in the signal bars box at top of phone. I've had this phone about a week and this is the first time I had no signal. I've been reading forums about issues with 3G working, but I haven't read about no signal at all. Any input you could share would be greatly appreciated. Did I cause this by some app I might have downloaded? Removing the battery for 10 minutes did not help. I do not live in a "high traffic" area. I have noticed the "time without signal" bug on this phone, which I learned about by reading forums...I don't know if this is connected to my complete loss of signal. Will I be plagued with this problems regularly as long as I have the Optimus V? Will rooting help? Should I return the phone for a new one? Lastly, I don't understand how to make calls without 3G. Is there a way to do that? Thanks so much!! Complete newbie and nontechy gal here...TIA!!!
