I occasionally mail screenshots to colleagues and clients from the official Google Mail app on my iPhone.
Apparently, it automatically scales them down:
The image originally was a 1.9 MB screenshot from the new iPad.
I checked the app and the settings but was unable to find a way to disable this behavior.
I had that configuration - and also used for friends & family - and it worked just fine.
The only drawback is that mail is no longer pushed to your phone. But apart from that, it's the best solution to have Gmail (actually working) and Google Contacts / Calendar on your iPhone.
You can try using an app like Photosynth, which creates stitched images from a set of images. Unlike some apps that only stitch panorama left to right, this allows for both up-down and left-right, which makes it a good choice for your purpose.
Using the latest in computer vision techniques, you can not only make a panorama from left to right, but also up and down, enabling you to capture a full “sphere”.

At the moment you cannot configure this. As an alternative you can use the native email app which will ask you if you want to resize large images and let you choose their new size.
