Looking at the specs for iPhone 4S (and iPhone 5) it says that the camera is 8MP. Why when I use the iPhone 4S camera, do my pictures save only as 2.5M?

How do you know its 2.5MP. And i'm pretty sure its a manufacturing fault. You will neet to send the phone back to apple for repairs.
When I look at the size of the picture's file, it is 2.5 megabytes. I need pictures that are at least 3 Meg to be able to have them print well in newsletters, etc. I guess this is a resolution issue: Does iphone take pictures in resolutions higher than 2.5 M? If so, how do i make my phone do that?
I thought you were talking about MegaPixels. You can't increase the size. You just need a bigger lens; so that means yo're gonna have to get a camera or something.
What, then does megapixel measure, and what does it do for pictures?
Megapixels and Megabytes are not the same thing. To print at magazine quality, you want to print at 300 dots per inch. Dots are not the same as pixels or bytes. Confused yet?
The iPhone 5 (and iPhone 4S) both have 8-megapixel cameras, which means their photos contain approximately 8 million pixels. A portrait photo is 2448 pixels wide and 3264 pixels tall, giving a resolution of 7990272 pixels. A Megabyte is a measure of how much space the photo takes on disk and will vary based on the content and complexity of the photo.
Your iPhone 5 photos are very likely good enough to include in a newsletter, even at a large size. The best thing to do is to print an example to make sure it looks good enough for you.
the pictures I take on my iPhone 4S save as 2.5 Meg. How can I get them to save as 8 Meg? (or at least 3?)
