Is there a way to turn of the GSM Radio, but still have the Wifi on? This would be useful if you want to take your G1 roaming, but control how it uses your data.

PS: It will re-enable the radio, but you have to wait 30-60 seconds after touching "turn on radio"
I have found that if you go to operator selection and select AT&T (assuming you're on Tmo) it will drop your connection to Tmo and because you have no AT&T service it won't connect to that either. It cuts service but I think the GSM radio is still on, just not connected to any network. You can select Tmo obviously to get back on their network.

I've searched the forums for an answer to this and I've found partial answers. I'm hoping I can get a response that will work for me.
Firstly, in the 'Bands' tab, I'm looking for some clarification on the options available. Under 'network type' there is 'Auto', 'GSM', and 'WCDMA'. Auto, I understand. GSM I'm assuming means GSM network (T-Mo, AT&T and not CDMA). WCDMA, according to Wikipedia, is basically the network that allows 3G speeds over GSM networks.
Now, when I set the network to GSM, I get an EDGE icon in place of the 3G. When I set it to WCDMA, I get 3G, as well I should.
First question: If I set the network to WCDMA, will it force my Fuze to ONLY connect to 3G? Where I live, I'm finding it hard to find a 3G dead zone to test without traveling 30 miles...
Second question: Does forcing 3G only improve battery life? I read in one post there are separate radios for 3G and EDGE/GPRS (which makes sense as to how you're able to talk and use the data connection simultaneously) and by forcing one, the phone doesn't constantly scan for the other.
My third question has to deal with having my device automatically disconnect the data connection after it finishes its business. I read in several posts that 'Advanced Config' has an option to set the data timeout, but I've read through the menus several times and have seen no such option. Are there multiple versions of advanced config floating around? Barring that, could someone just tell me what registry entry to add/edit to set the timeout? I read in yet another post that the phone automatically disconnects after 30 minutes, but that doesn't seem to be the case, as I tested mine and we're going on over an hour with no connection drop. (No email is being checked and weather is disabled. Prior to me starting this particular data connection, the phone had been connectionless for almost 16 hours.)
AdvancedConfig/Menu/More settings/Connections.
There is also that option in DiamondTweak.
WCDMA means 3G only, which means that your phone isn't searching for GSM signal. I haven't noticed battery improvement when forcing 3G, although that would be logical.
I`m sure that everybody has a problem with logging into gsm network when telephone loses range.
It is searching constantly network but nothing happens until in comm manager I switch off gsm and then tap "phone on". It`s not a radio rom issue. Tested dozens of radios. It`s rather a hardware issue. Weak internal antenna.
Is there any possibility to create simple script/program to do action gsm off/on automatically when telephone is out of range for example for 30seconds and more ?
So I work in midtown Manhattan, and in my particular building, ATT's service is very spotty, specifically where I sit. You'd think the 28th floor near Times Square would get great reception, but I don't. Oftentimes my network connectivity will go completely blank w/ absolutely no service, then turn back on. I've called ATT, switched to a 4G sim card, they pushed updates, rebooted my phone, etc. all to no avail. I still get very spotty service.
EXCEPT I just figured out if I have an app w/ streaming data running (run once there is an initial connection of course), it actually maintains the connection (currently using the streaming music app "di.fm" and "sky.fm", Pandora would prob work as well). I'm assuming this is because the phone locks onto a specific tower and doesn't let go as long as the app is accessing the data continuously.
Is there a way for my phone to stay connected to a specific tower and not jump around without running a streaming app? Any help would be much appreciated. Thanks!
I hate to say this but it's your area during peak times. I work downtown near the Brooklyn Bridge and experience the same thing. Until AT&T finishes the backhaul this is what we're stuck with. Build props and other mods are shots in the dark but won't help much.

Unless they give him a microcell.
Since they know you've been having issues, they might give you one for free.

But why am I able to maintain connection when running a streaming app? If traffic was the reason why my connection was dropping, wouldn't it still do so?
I think the tech guy said something about how my phone would try to connect to a tower 20 miles away when there are half a dozen right around me. When my phone does have reception, it's probably because it's hooked up to one of the close local towers, and running a streaming app forces it to stay locked onto that one...

When idle it's easier to drop connections as the phone switches frequencies. Here's a couple of things to do if you haven't done so already.
Make sure you're running the stock radio, if you haven't flashed another radio you're running the stock one.
Change to usa bands only. Open the dialer, press: *#*#4636#*#* Go to phone information. Press menu then press select radio band. Then select USA only. Give it a few seconds while it reconnects.
OK I'll let you know if it maintains network connection any better.
Also, what about the preferred network type? The options I have are:
- WCDMA preferred
- GSM only
- WCDMA only
- GSM auto (PRL)
- CDMA auto (PRL)
- CDMA only
- GSM/CDMA auto (PRL)
- Unknown
It was previously on WCDMA preferred, but should it be GSM/CDMA auto (PRL)?
I am with a carrier (U) that supports 3g in limited areas, outside the coverage, I will be switched to another carrier (C), but only with EDGE connectivity.
I am living in the 3g coverage area, but somehow the car park is not covered, so everytime I go to my office car park, it switches to C, and when I am back in the ground floor and up, I noticed that sometimes its very slow in switching back to the carrier U.
I have called U up and they asked me to use the "Select Network Automatically" settings, but that doesn't seems to help much as sometimes even after 30 minutes it didn't switch back, until I go into the network settings.
I have noticed this too.
I an on Sprint. If my phone switches to 1x cdma (slow), it may not switch back to 3G if I am actively using data. I have to uncheck and recheck "data enabled" to bump it back. It seems to switch back ok if data is idle.
hmm, wonder if I could do something with tasker about this.
I borrowed the SIM card out of my AT&T 4G/LTE hotspot to see if I could turn my old phone into a hotspot. However, while it does connect to the network, it will only run in HSPA mode. I briefly got it to use LTE for about an hour, but the ROM was still randomly rebooting then, and I lost it on reboot. I did put the SIM back in the hotspot, and it does get 4g/LTE on that device, so it's not the SIM card or the service as near as I can tell.
I did try to use the *#*#4636#*#* menu, but it instantly reverts back to WCDMA preferred if I select anything other than unknown. The same happens if I attempt to switch to LTE in the mobile networks menu. I also tried setting the APN to AT&T Broadband (the APN used by the hotspot) as well as AT&T LTE. I found an older thread related to this, but there didn't seem to be a conclusion.
The only caveat here is that the SIM is only authorized for data, not voice or SMS.
Any ideas?
