Hi all, I only have limited room on my iPhone so when I complete a game I need to delete it to make room for other games. However, when an update comes later for a game I've completed/deleted, in order for me to play that update (i.e. new levels) I have to reinstall the game on my phone, but by then none of my progress has saved, so I have to complete older levels in order to play the new ones in the update. The only solution to this is to keep the game on the phone but then it takes up uneccesary space and much needed mb. I've never tried iCloud or even really looked at it because I don't have an iPad, is this the solution? Even still I havn't seen many games (if any) that have it. Anyone know a solution to this? I wish the phone saved game progress when the app itself wasn't on.
What a game does with saves is entirely up to the developer. Some games use iCloud, some can estimate progress from Game Center (Death Rally is one, I believe), some free up saved games for you to extract via iTunes (aka Junk Jack). By default though, deleting a game will delete save games too. It's a bit unfortunate, yes, but that's how it is.
You can try using something like iFunBox to backup the app data on your computer, this has worked for me.
To summarize: If the game uses iCloud (or saves to another server), you are all set. If it doesn't, and you haven't jailbroken your device, there are a number of Mac and PC applications that allow you to see into the device's file system. I use PhoneView, but there are also several free apps as well (iExplorer, for instance). Just go into the device application file and find the Documents folder, then copy the contents to your PC. Apparently iFunBox allows you to do automatic app backup, but I haven't tried it. To reinstall the save game data, just redownload the game to your device, then use the file viewer to replace the content of the Documents folder with your back up. If you are jailbroken, use appbackup (as posted above)
You can back up any app without jail breaking pretty easily. I do it all the time. Use iexplorer, (google it) connect device to pc, go to the game, go to documents, drag and drop them where you want to save. TA-DA! The save file backed up. Experiment around a little until you get the hang of it.
