will i lost my save when i delete the game on my iphone?

my iphone has run out of spaces. i need to delete some old games that i finished for some new games. if i back up, than i delete it from my phone, will i still be able to restore the game save later if i put the old games back in my phone?

Unfortunately they'll be deleted if you delete the game from your iPhone. Only solution is if you jailbreak and save the game data files on your computer.

It depends on the game. Some games save their game state with the complete profile online using Plus+ or OpenFeint. Some save the score online in Plus+, OpenFeint Game Center or CloudCell and are able to restore at least the score after reinstalling the game. And some games allow to download and upload the SaveGames via the file sharing of iTunes.

But for most games you will loose your progress. That’s why I never delete Tap Tap Revenge and geoDefense

tap tap revenge will restore....

YES, game developers should be more clearly about what they safe in the cloud.

I know plus+ can store savegames (Warpgate) and GameCenter can do saves, too (Gun Brothers) while games with exclusive OF might just be able to store your achievements and score etc.
