Following a long wait for their Xperia X10 smartphones to receive an OS upgrade from Sony Ericsson, many users would be disappointed to learn that the long promised Android 2.1 update won't come to their devices before the end of October.

Previously, the company announced that the new OS flavor would land on its X10 family of devices, including Xperia X10 and Xperia X10 mini and X10 mini pro, before the third quarter of the year is over, but it seems that things changed in the meantime.

“We have earlier given some information on what to expect from this update and said that the roll-out was planned to start late Q3,” a recent post on the Sony Ericsson Product Blog reads.

“The plan for the added features and Android 2.1 step-up still holds but unfortunately we need a couple of more weeks before we are ready to start the roll-out. The revised plan is to start the roll-out from end of October and onwards,” the post continues.

The company's devices came to the market with the Android 1.6 operating system on board, even if they were released at times when other handsets got Android 2.1.

However, Sony Ericsson did promise that the 2.1 update will come to its phones, and it says that the plan still is to make the move, though things have got delayed a little too much for some, that's for sure.

According to the company, we should expect for the upcoming OS update to bring some nice enhancements to its Xperia X10 devices, which changes differing from a phone to another”.

"The key changes for the different products are the following:

Xperia X10:

HD video recording with continuous auto-focus for high quality videos Upgrade of the Android platform to Android 2.1 New backup and restore application, with extended content back up 5 homescreens for apps, widgets, shortcuts and folders Social phonebook which automatically syncs contact pictures from Facebook and shows when your friends are online

Xperia X10 mini and X10 mini pro:

Improved Bluetooth functionality with support for sending and receiving pictures, contacts and more New backup and restore application with extended content back up Automatic synchronization of your contact pictures between Facebook and your phone book Improved ways of handling pictures, audio, text and numbers in your messages Upgrade of the Android platform to Android platform 2.1"

In order to keep users close to the Android 2.1 update for their devices, the company plans to provide a series of videos with these phones running under the new OS version.

Hopefully, the Android 2.1 OS will indeed arrive on Sony Ericsson Xperia X10 devices out there by the end of the next month, though it remains to be seen whether carriers will also start rolling it out at that time.
