The same thing just happened to me. I bought a 9860 on ebay and it was from at&t. I'm with bell in Canada. Called RIM and they have no idea how to fix it. Until 5 days ago it was the best phone I ever had. I think we got ripped off.
*I think we need an article on CB about this. This could be a big issue for many people !!! *

I do not have an AT&T phone and I am not on the AT&T network. What you guys are seeing would appear to be unique to AT&T phones even if thet are not connected to the AT&T network. Please can someone confirm that this is true.
For now, I shall assume this to be the case. There are only two ways that an AT&T phone can be made to work differently from other phones on other networks. One of these we may eliminate immediately. This is Service Books. Since it is not AT&T sending these they will not affect an AT&T phone.
The other is to ask what gets loaded at OS install time. This is defined by two things.
- The phone model. In this case it's a 9810.
- The VendorId of the phone. Type <Alt><LeftShoft>H to see this. The VendorId is defined at manufacture and cannot be changed and each carrier has an unique number. This allows RIM and carriers to identify their phones at OS install and other times.
Carriers can load apps, themes, ringtones and specific .cod files at OS install time based upon the VendorId. I found a file in the Java folder called
net_rim_hotspotclient_att.cod and I wonder if this may not be affecting the hotspot and maybe other network parameters. There is no other file called net_rim_hotspotclient that I can find.
I suggest a trial removal of this file by using CrackUtil http://forums.crackberry.com/f35/crackutil-85617/ or BBSAK to remove this file. If you use CrackUtil, please make sure that you read the specific instructions in my first CrackUtil post for installing under Windows 7.
The removed file will be placed in the CrackUtil folder so you can easily put it back.
I have NO IDEA what will happen here.
the file net_rim_hotspotclient also show up in 7.0 os, so I think it will not fix the problem
, there is two files ,net_rim_bb_manage_connections and net_rim_bb_manage_connections_lib
I guess that at&t modified them.
is it possible that I loud the two files of 7.0 os into 7.1 os ?

And yes, I can confirm it will switch to EDGE when necessary.
I was concerned too about not having the option to choose as I live on the 4G fringe zone but I have found .391 to be very efficient at choosing the network. BTW... battery life does not seem to suffer... I'm able to get 2 full days without a recharge while constantly going in and out of 4G coverage. I can't confirm this but this build does not seem to make the device 'hunt' and drain the battery. It just uses what ever is available. I'm happy!
