Image tiles on iPhone 4
<p>I am very new to iPhone development, and I am working on modifying an app which was written a year ago. Recently with the release of the new iphone 4 we have noticed that the screen which was previously displaying an image just fine, has not started to tile that image. And instead of one large image I am now seeing 4 smaller ones. I have tried increasing the size of this image but that does not help. Anyone know what this can be? Resolution? How do I fix this?</p>

<p>Thanks,
Natasha</p>
