HTC Flyer quietly gets over-the-air software update, promises to 'improve system performance'

No, it's not an upgrade to Honeycomb, but the HTC Flyer is getting some tweaks nonetheless. Over the weekend, owners of the 7-inch tablet should have seen a prompt for an over-the-air update making the vague promise to "improve system performance." We're naturally all kinds of curious, particularly given that the battery life and overall performance were already pretty solid. Flyer owners, are you noticing any differences? Do tell.
