Problems with Notes on my iphone

I love the Notes "app" that comes default with the iphone. However, I've been having problems with it, now that I use it a lot and am able to observe the smaller details.

I see that there are two forms of Notes, those linked to my email and those "on my iphone". Right now I have the setting left as "on my gmail", so the notes get backed up there every time. This is good, since I have the annoying problem that I can save a note on the iphone, and the next day when I try to access it, it is no longer there (although I can find it in my gmail account). Worse yet is that I can already have a note saved, go into it later to add something, and before my very eyes the system will update (or something) and the information I've just written in will disappear.

Please help!
