Sometimes when Gmail’s IMAP or Push interface isn’t working properly within the Mail app on the iPhone, you can always fall back on the HTML5-powered web interface on your iPhone. If you’re looking to search within your Gmail, the web version is definitely your best bet.
The Iterative Web App: New Auto Expanding Compose Box
Looks like the Google team is improving Gmail on the iPhone once again. Previously, when composing email you would have to use the magnifying glass to scroll down.
