When Nokia released the newer Symbian Anna and Belle updates for later phones (like the Nokia N8 or E7), E72 users were desperate to get that look. Developers created "ported" themes that mimicked the rounded icons and modern UI of the newer OS on the older E72 hardware. These were often labeled "BEST" because they gave the aging phone a fresh, modern feel.
The E72 was a business phone, first and foremost. It was used for emails, documents, and messaging. A theme that looked cool but made white text unreadable against a light background was instantly deleted. The "BEST" themes were those that balanced artistic flair with functional readability, ensuring that the AMOLED screen of the E72 popped with color while keeping text legible.
