Palm Centro, not getting any service!

Hello to all.

First of all, my first Palm phone just got it today and already unfortunately thinking about switching back to Blackberry.

Got the phone, charged the battery, texted and called some people for a bit to test it of course, worked like a charm! Then I synced it with my PC (XP) everything was fine, no problems there. After awhile I get a phone call, i answered it talked for about 5 mins and all of sudden lost contact and the phone it seemed as it froze. Couldnt hang up but it was showing still as I was talking to the person even the call timer was still counting. Then I was trying to hit different buttons but no respond. I was holding the power/end button and eventually reboot it. When it came back on, at the left upper corner says Phone Off and red light indicator is constantly on as if is I was charging the phone but the charger wasnt plugged. Then I hit the power/end button to swtich it on, then AT&T screen pops out and says Hello but still says Phone Off and the red left corner light is always on. Called the service dept. they couldnt figure it out they were telling me is because of an outage but my brother that lives here same area has an AT&T and his phone was just fine. Did a soft reset like 10 times, no luck. Then did a hard reset, same thing. Im out of ideas. Is it something that can be fixed or the phone is gone and should probabaly send it back and get a new one?

 

Thanks in advance.
