Connection Issue (AT&T) Help!

[Willieg]

I have had my dual for the past 3 weeks and it has done great (even with out 850 on the AT&T network).

Yesterday I took a driving trip to another location (about 2 hrs). The entire trip down I was monitoring the connection on the phone and it had ok connect. At one point I made a call on the phone and it was great call quality. About 20 min later I went to make another call and the phone had not connect (radio Icon with constant dots or !). I thought I had just wandered into an 850 zone. So the entire drive back I had no connection (where I had had it on the way down). Even at my house I have no connect. It will not connect with the AT&T network anymore. I called AT&T and "registered" my IMEI number just in case they had locked me out (they said they did not).

I have taken my SIM out of my Dual and put it into my Cingular 8125 phone and it works like a champ.

I have also done a hard reset on the Dual.

I hope I did not throw $$ power the toilet.

Any Thoughts??? Any logs to look at??

Same issue here. Using my Dual for 2 days now. Everything worked like a charm (phone, 3G-internet) and then I was travelling by tram (few km) while surfing and then... you know it.

No connection for several hours, network scan shows all available networks, but connecting failes. Several soft-resets didn't help either. Done a hard-reset a minute ago: didn't help. Using the same SIM in my old Magician I experience nothing but a fully working phone.

So... I gotta return that Dual to O2-Germany tomorrow, hoping to get a working one soon.

Cheers,
jekk.

//update
just got connection after a soft-reset.. but... here is how:
1. soft-reset
2. entering PIN
3. Dual searches...
4. And after 3-4 seconds, it connects!
5. after again 3 seconds it recognizes 3G
6. after another 3 seconds it looses the connection. Damn sh*t.

// another edit... looks like this is becoming a monologue, uhm?
Since I do not want to give my Dual back to O2 I searched a bit and have come to this solution:
Changing the phone settings does the job. Go to Settings->Phone->Band and choose the appropriate values. In my case there are W-CDMA issues, since sticking to GSM solves my problem. Nevertheless, this is not the way I wanted to use the Dual, if I CAN have 384kbit (no HSDPA around), i WANT it. End of story.
Tomorrow I'll tell O2. I promise. :mad:

// update 3
This is obiously turning into a monologue now, but now I know why:
This wasn't an issue with the device. After calling the hotline several times, it turned out that my access-rights to the umts network were altered accidently. The man on the phone did a usual check of this today and changed it instantly and after some minutes the problem and was gone. So to summarize:
Everything is fine with my touch dual. :D
