Motorola’s Xoom will get the promised 4G LTE modem upgrade in September, per corporate communication from Verizon Wireless sent to registered users, published by the Droid Life blog. The free of charge update promises a tenfold increase in network speeds, available to more than 110 million people in select markets where the carrier rolled out its 4G LTE network, with “coverage expanding every day”. The email notice reads:

Be on the lookout at the end of summer for an email with information about how to upgrade your Motorola XOOM to speeds up to 10X faster than 3G. In the meantime, learn more about what you can do to prepare for the 4G LTE upgrade to your Motorola XOOM by backing up data, encrypting, or resetting your Motorola Xoom tablet.

On a somewhat related note, T-Mobile and Sony Ericsson also began rolling out Gingerbread updates to the Xperia X10 and G2x

T-Mobile announced on its support forum that Android 2.3 Gingerbread update is rolling out over the air to owners of the T-Mobile G2x smartphone, made by LG. The software brings improved battery life, better handling of front-facing camera operation when using Qik record and share and improved disabling Car Home. It also helps address unexpected reboots. More information about the update is provided on LG’s web site. Also, Sony Ericsson said that Android 2.3.3 Gingerbread update is ready for the Xperia X10. It brings Facebook inside Xperia (“a series of unique integrations of Facebook into your multimedia apps, phonebook and calendar”), WiFi hotspot functionality, music player with equalizer, USB tethering, the new Photo widget and app tray sorting. The update will replace the current software and wipe out all user data so you should back up your phone prior to upgrading its software.
