This is my first time having an android phone and I just switched from Apple to Android. In my Iphone4, to get games, its either I buy it from istore, or option B , I jailbreak it and download the games I usuall pay for for free from Installous.

Now my question is for Android phones, how do you get games by PURCHASING? Whats Androids equivalent of apples istore? And second, Is there a JAILBREAK equivalent for Android phones like in Apple iphone4 and I just download free games in Installous?

I prefer buying but as a new Android phone user, I want to know both option, can anybody please help me? I'l give 5 stars for best answer.
