Can a game be designed to run on the iPhone 4 and also run on the iPad without any changes? I know the screen resolutions are different, 960x640 for iPhone 4 and 1024 x 768 for iPad, but I have heard iPhone 4 apps run on iPad.

yes, it can. but if i were you, i would make a check device installization at start up.
So your GUI and what not, is aligned right.
So yeah, i should run on both, but, to make the best out of the app, i would add a few extra lines, which wouldnt take more than an hour, to make it fit for both devices.
the new screen was no win, that was an as ugly punch into the face as the ipad already as apple again went with the 2009 GPU which is nowhere capable to feed 960x640 with a reasonable amount of transparent surfaces (you can render the ipad screen 2.5- 3 times pixelwise, for the iphone 4 its slightly higher but the iphone 4 takes a hit as the cpu is only 800mhz, not 1000mhz as the ipad one so you lose on the geometry end again which was required to compesate for the fillrate dillema)
its a bad joke especially cause apple likely had access to the successor gpu, the SGX 545, since nov or dec as major customer and investor in imagination technologies.
I’m in the midst of my 2D game and am worried and confused about these now 3 different resolutions we have to contend with:
iPhone 3/3gs iPod Touch
iPhone 4
iPad
What resolution should my textures me to accomodate for all 3???
I currently have been working with 480x320 (GUITexture) and 512x512 in other areas with meshes…
If I start using 1024s to account for all devices, won’t it be too big for iPhone 3GS?
I’m a noob, so bare with me please and be nice 
Cheers
Been doing some thinking and I’m seriously considering making one app for iPhone and another improved version for iPad. Since my app is “all about the art”, presentation is the most important thing and I can’t afford risking the images being stretched or not presented perfectly.
What do others think?
And does anyone know if when someone purchases either the iphone or the ipad version, they have to purchase the other if they want it or can they receive it for free (can apps share a ‘product code’ as such?) I really don’t agree with people having to buy apps twice for 2 different methods of viewing… it’s not right. Any advice?
If you are making separate apps people will have to buy both. I would say that is why if you are going to do a ipad app you should make use of the power the ipad gives you. That way people do not mind buying it twice. I bought plants vs. zombies for my ipod and then I bought the HD version for my ipad. I can say I am not disappointed with either purchase.

And charge more for your iPad version. People should be willing to pay a little more for a larger screen and higher resolution art.
