just for som phone noob, it could tell you you are on the lasters firm ware however that is because oyu have a branded unit running network tampered firmware, you need to wait for them to tamper with the new firmware before you can update, and the only way you can run the latest when it s the latest is yo flash you phones with sony ericsson generic software, this makes the phone what it should be withought he orange/vodaphone or t-mobile, logos and disabled setting etc. i debrand any SE i get they are usually abit more stable than the branded ones.
