The one trick that works with most 2.1 Eris ROMs is the airplane mode trick. All you do is put your phone in airplane mode for a little bit and turn airplane mode off and it fixes the issue.
Basically all this app does is upon boot, puts the phone in airplane mode then waits 12 seconds and then turns off airplane mode. Finally, it kills the service so it won't run again until the next reboot.
I know it's not elegant or anything, but it seems to do the job. There are no settings and there is no icon for the app. Just install the .apk and reboot your device.
Please let me know any feedback you might have... good or bad. Thanks!
2/2/2011 - v1 - Initial build. Seems to work fine on xtrROM and xtrSense.
Added some checks to make sure you are not already in airplane mode upon boot.
