Hi, these days i being seen games like CREATURES or AFTERMATH that only works on 4.0 and that really bother me. I have a 2nd generation iPhone and my firm is 3.1.3 so, you know any way to make that games works on 3.x firm? Please help me.
If 2nd generation iPhone you mean the 3G, then just update through iTunes to 4.1. Jailbreak is also available. If you are referring to the original iPhone, then take a look at the whited00r project (custom 4.x firmware for older devices).
Why don't you just update? Just because some of the features don't work doesn't mean it's not usable. :b
