Bay Area Hermes/TyTn users...

[pkx]

I also posted this over on howardforums. Thought it might be device specific, so I'm posting it here as well.

I just got a TyTn (628 s/n). I live and work in North San Jose, CA. When I turn on the phone, I get the "U" (UDMS available) for a few seconds, then it goes back to "G" (GPRS) and never returns to U.

I've stood a few hundred feet from a known Cingular 3G UDMS tower (corner of Nortech Pkwy & Disk Dr, San Jose) - same results...

I've "only" got the Media Net unlimited plan, and I'm connecting to wap.cingular. Could this be the problem? They're denying UDMS access to my account based on my data plan? Should I upgrade to PDA Connect?

Thanks!

Naw, I was in San Jose this weekend, and 3G was pretty spotty, except in certain places. At my friends house, I had 3G completely; but it was a HUGE battery waster. So unless I'm tied to a charger, I wouldn't use my phone very much in a 3G area. Unless they release an extended battery that is. I'm also on the $19.99 plan, and I was averaging about 600Kbps with 2-3 bars. You're fine on the data plan.

Hm, thanks.

I had full battery when I left around 2pm, a little browsing, speed tests, and push e-mail, I was at 20% around 9pm...that's really bad :(. Granted, I did have the backlight on a lot, and even had a few calls come in, so that wasn't just on standby. But I think it's the same drain as WiFi would be.

That's ridiculous. I thought my Treo was bad..

Between battery life and lack of a good mail client, this might have to go on ebay :(.

[darkjedi]

Granted, I WAS using it a bit, so I can see why it drained, but it's a bit much if you ask me. So I'd only really use 3G if I had a charger or an extended battery (which I don't think they do).

Install the field test utility and tell me what do you see in the "2G reselection status" when it goes to G. San Jose is well covered and the opposite should happen i.e., G for 1 or 2 seconds and then U

:)

We are founding in many instances exterior interference from illegal repeaters and some lab equipements which are causing a high level of noise in some cells forcing the phones to reselect to GSM.
While on GSM a 3G phone always scans the UMTS band in the background searching for good signals ( good signal strength and low inteference ). If the inteference ( measured by Ec/No) is high it will not go to UMTS

First of all, thank you for your help.

I just went back to the HTC firmware since the Cingular didn't do anything for me. All of the field test options just say N/A - Do I need to go back to the newer Cingular firmware for it to work?

Thanks!

I'll be in San Jose next week to see how the HTC ROM goes.

Push email with 3G is a battery killer ...

[darkjedi]

That could be it as well, as it was enabled the whole time...

Update: Got a 3G SIM from the Cingular store and it works great now :).

[darkjedi]

I figured as much :) That's great news :D
