After Thursday’s launch of the iPhone 4 I discovered a couple of glitches in the sign-in that stopped users being able to log into their Upcoming account on Happening. The fix is in v1.2.4, that also includes a fair amount of new - hi-res - iPhone 4 artwork to make sure Happening looks its best on the new hardware.

Apologies if you were affected by this issue: the update is rolling out to the App Store as we speak (and thanks to the App Store approval team who turned this approval round in two business days).
