It’s a disaster.

A better situation, you didn’t meet the problem, but your stuff is full, can’t fill any apps, or music, what should you do?

you’ll need some alternate strategies. Here are some ways to choose what to sync, and how to save space going so.

How much space do you have?

iPhone The iPhone comes in 8GB (iPhone 3GS) and 16GB or 32GB (iPhone 4) capacities, or only half as much room at the high end than the iPod touch or iPad.

iPod nano You can get either an 8GB or 16GB nano. This holds a fair amount of music, but not a lot. (Though the way the space is calculated means that only you have about 7.5GB or 15GB, respectively.)

iPad iPads come in 16GB, 32GB, and 64GB models, but like with the iPhone and iPod touch, since you’re likely to put a lot of apps or videos on it, there’s less room for music

Select playlists, albums, artists, and genres

For any good-sized library, checking and unchecking songs may not be the most useful method of controlling what does and doesn’t sync. An easier way in that case is to choose specific playlists, album, artists, and/or genres to sync. With your iPod/iPad/iPhone connected to your Mac, click on the device in iTunes, then click on the Music tab. You’ll see options to sync your entire music library, or selected playlists, albums, artists, and genres. If you check this latter option, you’ll see four sections on the screen that let you check or uncheck that content you’d like to copy.

The method is very useful for copying just parts of a large library to a portable device. I do this with my iPod touch, selecting certain artists and playlists, and I have a special playlist, named iPod, for adding occasional tracks or albums that I want to sync. When I remove them from that playlist, they no longer get synced.
