I'm taking my iPhone 4 (16GB, GSM) into the Apple Store tomorrow to see if I can get the battery replaced. As per Apple's recommendation, I did a full, manual backup to my computer.
When I back up my iPhone to my computer manually (I normally use the iCloud backup), however, I notice that suddenly all of the free space on the device evaporates. Nothing new was added; in fact, I wiped my camera roll (which had about 800 MB of pics/vids in it) and ran the back up again, and it all disappeared. 3.4 whole GB are now eaten up by the "Other" category, easily three times larger than it was before.
I would really appreciate a solution, as it has made it impossible for me to download podcasts. :-(
Thanks,
Nate
