Bugs on version 3.7(20) on ios6

Hello, from yesterday when I try to run the version 3.7(20) on my iPhone 3GS with iOS6 I have a "new version game" popup with only one button to update the game.
Unfortunatelly the new updates are desiged for iOS7 so I can download the last compatible version -> 3.7 (20) ... (the same version)
after the new installation when I run the game, it give me again the "new version game" popup ...
it is a loop and it is not possible to play to City Domination with iOS6 with last compatible version.

Could you please add something like "reminder me" buttom to skip the "force update"?

(I don't want to buy another iPhone only to play to this game...)

Thanks.
Best Regards,
Fabrizio

Hi, devs gave up iOS6 support Sorry for you.

Is it possible to download a previous version 3.6 for iOS6?
Is it run with the newer database (not all new feature run obviously)?

If yes for all previous query, where do I find it?
(I try on iStore but i don't find it)

Thanks.
Best Regards,
Fabrizio
