Updated Sony Ericsson has officially released software updates for its technically troubled Satio 12Mp cameraphone and Aino 'PlayStation' handset.

The company hasn't said much about what changes either update makes to the two handsets, except to promise that Satio's update provides "better performance and core stability improvements".

The Aino update reduces battery consumption and adds "performance improvements for GPS, WLAN and Bluetooth", the company added.

Oh, and SE has also bundled "hit" game Loco Roco in with the Aino update.

Both handsets have attracted some bad press over the past few weeks. Satio was withdrawn from UK sale during late November after SE admitted that “a small number of consumers have experienced software issues” with the phone.

Just a few days later the company was forced to cough up to a “software issue” with Aino, though the phone wasn't withdrawn from sale in Blighty.

Users must download SE's PC Suite software in order to apply either the Satio or Aino patch, and it's worth pointing out that you will lose your stored messages, games and phone settings as a result.

Both updates could also affect applications, music and ringtones, SE warned.

Full patch download details are available online now.

A software update for the Yari handset will also be available soon, though it's unknown at this stage if the phone suffers from Aino/Satio-esque technical troubles.

Update

Scott Hooton, Trading Director at Phones 4 U, has since confirmed that its Satio stock "has been flashed with new software". ®
