If you hadn't noticed, there have been a lot of app updates to accommodate the launch of iOS 7. You may not have to use a WiFi hotspot to grab them all, though -- Apple has quietly raised iOS' cellular download cap from 50MB to 100MB. You won't be loading Infinity Blade III while on the road, but the ceiling is high enough that moderately-sized apps like Sky Guide are now available over the air. Just make sure you've got enough spare bandwidth.
