Finally saw the new working version of Android 2.1 for Sony Ericcson Xperia X10 on my brother-in-law's phone. He bought it for his wife to replace her old phone. The size is nice for her but she need to get use to the touch screen though.
Anyway, I wanted what were the major difference with the current Android 1.6 version of my Xperia X10 mini pro. From what I could, is mostly cosmetic wise as the usage is still the same basically with all the same function. However I'm still considering it,as some software that I have runs only in Android version 1.6. So I'll just have to think about it.
Finally updated my Sony Ericcson Android version to 2.1. It works much better now though the version is still behind 2.3 versions flying around in the market. However for the SMS text message, I'm not able to forward them. The message software will crash. The workaround way would be to copy and paste to a new message. Probably a bug in the software. Otherwise, overall the new updated version functions pretty well.
