Update to R67-4 is out and it's causing issues:
I've got the app on two different phones. One phone (which has an AT&T SIM in it) auto-updated to the latest version, which then broke the app with the not approved in your country/carrier message. I uninstalled the update from the Settings/Apps menu on the phone, and restarted it. All my user info had been wiped, but I was able to re-register without issue...and then the app immediately auto-updated from the Market/Play Store again. I repeated the uninstall of the update and quickly located the app in the Market and unchecked auto-update. I then used Titanium to try to detach it from the Market, but it still keeps showing up in My Apps and lists as an update available, even after a reboot. I'm afraid one of these times I'm going to screw up and hit update all.
The other phone, no SIM in it, did not auto-update, and Wallet doesn't even list in the Play Store on it. The app was installed the same way on both phones.
I wonder why it lists in the Market on one phone, and not on the other, and why detaching doesn't stop it. Is it because it's a system app?
