The Google+ iPhone app was updated yesterday, to Version 18.104.22.16840 (hilarious Google, not getting old at all this crazy version numbering).
This update adds full resolution photo uploads, search, photo + 1 and unspecified bug fixes and performance improvements.
What it doesn’t add is an iPad app. It’s still not a universal app so on the iPad you still have to run it in 2X mode. For me, Google+ seems better suited to the iPad than the iPhone – so not supporting the iPad would seem an odd choice if not for all the bitter rivalry between Google and Apple. I expect we’ll see an iPad version at some point, I just don’t expect Google to be in much of a hurry on it.
