I read that there are some adapters and wireless sdcard devices such as the Kingston MobileLite Wireless to connect the iPhone/iPad. If the files created by Application X can only be accesses by Application X, can I do the following:
1. Save all the files that I want to share with other applications, created by Application X, to a sdcard.
2. Save all the files that I want to share with other applications, created by Application Y, to a sdcard.
3. Save all the files that I want to share with other applications, created by Application Z, to a sdcard.
Access these files from any application through the sdcard. This way, even there is no wifi, it can still share files among applications. Can this be done?
