iOS5 and Large Map Caches

[Virgil Zetterlind]

EarthNC Power Users,

We learned today that in iOS5, Apple has changed the behavior of the
"Cache" folder. Data stored in this folder can be randomly deleted
when you start to run low on disk space. This effects EarthNC Marine
Chart Apps because we store saved maps in this folder.

We learned about this because the developer of Instapaper ran into the
issue and blogged about it:
http://www.marco.org/2011/10/13/ios5-caches-cleaning

We are now working on a solution. There doesn't seem to be an easy
answer - on the one hand, we could start saving everything in the
Documents folder, but then this data will be backed up to
iTunes/iCloud. This becomes problematic because it will make backups
take many hours if you have several gigabytes of maps stored. We
actually did it this way years ago, but moved to the Cache folder once
it became clear that backups were too slow.

We hope that this doesn't become a huge issue, and we will push a
release to fix this as soon as we can.

Regards,
Virgil

Virgil, I got a new iPhone 4S so I think I need a new provision file.
Right?

Rob,
Yes, I'll need your UDID for the new phone to add it to the beta builds.
