If you are planning to buy this, then you are planning to pay for an outdated andriod mobile, as Sony Ericsson has no plans to update the software of this, and thus you cannot able to enjoy the actual andriod.
Now the mobile can be updated only upto andriod 2.1, which is already outdated. Now u will get cheaper mobile with 2.2 and 2.3. so better to buy that..
I am suffering from this. Low battery backup, slow, no space to install software ( as 2.1 supports only to install in mobile and only from 2.2 u can install sw in sd card)
