It looks like today is a great day to be an Android fan. Earlier we found out that HTC was giving us the source code to the TBolt, and now, Sony Ericsson hit us with the news that they will be offering unlocked bootloaders for several of their new Xperia line of Android smartphones this year. The phones they mentioned specifically are Xperia Arc, Play, Neo, and Pro.
There will be quite a few restrictions on some of their devices. One example they noted was that devices locked to a specific carrier will not come with an unlocked bootloader. There are some other restrictions that they haven't fully disclosed yet. This probably means that the only unlocked devices will be unsubsidized and carrier-free, and they will be full price. Although that will be more expensive, it makes sense that they would do it that way. It's still nice to see a manufacturer actually listening to their customers.
