Google Wallet has been updated with a pretty extensive (and detailed) change log. You can now use a PO box in the address and be able to top up your prepaid card, and that address can be longer (good news for those living in Winchester-on-the-Severn, Maryland), reward card syncing has been fixed, "improvements" have been made to support more handsets, and fixes to the core wallet system have been applied.
One thing that hasn't been fixed is the prepaid cards. You can't add a new one, you can't retrieve your data for an existing one, and you'll get an error about system upgrades if you try. I know, because i tried both. I'm getting the feeling my $11.40 is gone forever.
All kidding aside, I'm sure some of you guys did drop a decent amount of cash in the prepaid card, have wiped your phone since, and can't get it back. I understand the need to change and fix a few things on the security side (Google Wallet is still very beta after all), but it would be nice to be able to access my fortune next time I wanna buy a cup of coffee. We can only hope Google gets it all figured out shortly.
There's a link after the break to the Market, but be warned -- it only will work if you've got a Sprint Nexus S 4G or an unlocked Galaxy Nexus with an AT&T SIM card in it. The rest of us will have to resort to hackery to get it installed. I'm sure the apk will be posted somewhere soon enough.
