What an incredible phone. Had it about a week now. I can find no fault. This might be up there with my old Nokia E71 as the best phone I've ever had.
Got a tempered glass screen on the front (can highly recommend the Casebase one (twin pack) on Amazon), and some makeshift 'titanium' effect vinyl on the back to give it a bit more grip.
Got a Magnector cable which is decent, magnet could be a bit stronger and do a better job of aligning itself like the Macbook Magsafe connector, but not bad.
Also got the Sony noise cancelling earphones (MDRNC31)- the noise cancelling works ok, sound quality is better than average, but overall just 'ok', and although clever that the microphone is built into the earpiece, I miss an inline module that would have also provided next/previous track and volume controls.
I've installed Nova/Apex and fiddled about as usual, but have just gone back the the Sony UI/Xperia launcher, it's really really slick, and not bloated at all. Touch wood won't have any glass cracking problems.
