(I'm a newbie myself, other feel free to correct me)
Create a context - CGBitmapContextCreate
You decide how big it is- it can exceed the iphone screen dimensions.
Draw your image and text into that context. (You will likely need to scale your font programatically to match the resolution your are drawing into.)
You can turn it into a new high res image to display with [UIImage imageWithCGImage:]. This is the image to save/email.
If it is less than 1024 pixels in any dimension, you can add it to a 480x320 imageView and have the view automatically scale to fit. If it is too large, you will need to scale it on your own.
