I was looking at the new firmware R5B02 release notes when one sentence caught my eye: "Improved visualization of the stand-by clock". I was curious what the difference was until I read the next sentence. It turns out the clock's digits are now larger than before! Silly me
On a more serious note, the update looks good. Lots of fixes, including improved Bluetooth, improved photos, improved handsfree sound, and fixed auto-caps in T9 text prediction.
