The folks over at O2 have been busy little beavers today, first releasing the HTC Tornado-based Xda IQ, and now posting the Windows Mobile 5.0 AKU update for Xda Atom owners to download. We're sure that we don't need to repeat the advantages of AKU2 again, but since our contracts stipulate that we rehash the deets ad infinitum, we'll remind you that this upgrade adds BlackBerry-like push email through the Messaging & Security Feature Pack (MSFP) along with an improved wireless connection manager, quicker screen orientation switches, and other minor enhancements. Atom owners also get a few device-specific bug fixes with the new firmware, most notably the elimination of the "heartbeat noise" that had apparently plagued some versions of the FM tuner app. For now you'll need your handset's serial number registered with O2 in order to access the download, but it'll probably be just a matter of time before it becomes available on one of the popular cellphone forums.
