I don't know why you're all still using Paul's modded APKs on your Nexus 4s. Installing from the Play Store and using Market Enabler allows you to use the stock APK, regardless of you location. I've been doing it like this for over a year with my Galaxy Nexus, and 2 months with my Nexus 4, allowing me to update Wallet straight from the Play Store on my phone, just like any other application
The issue is how we're going to get payments working again outside the USA. Nobody seems to be talking about that anymore.
People are mentioning that they're adding prepaid cards into Google Wallet. Could someone who has successfully added a prepaid card tell us which company they got it from? It seems like this is now the only option for those outside the US.
Yes, this is what you need to do. I would test it, but I'm away at the moment.
Use a US address so that the Google Wallet application picks it up and adds it. Once that's done, log onto wallet.google.com from your computer and change the address for the card to your full UK one. Google Wallet should sync updated card information as soon as you open it - I tested this by changing my name on the card in wallet.google.com, and the application automatically updated the name on the card.
