Since 5 months, the Xperia go is with me in use. Bin metal artisans and thought that so iss'es a cell phone is needed! Unfortunately, I have probably caught a model that still has various teething troubles: very modest battery life, mediocre camera (5M-pixel ...?) And most importantly, connect to the (O2) network is lousy. Thought it zzuerst present = 2, but my daughter (with i-phone) is our home in the apt. Full transmit and receive performance, while with me not 'beam' lights, thus also goes nothing! Neither receipt nor rausrufen! Must I now after 5 months probably set another device, so I can at least call and am available. Max 2 stars! As of August 2013: now the unbreakable 'Sony Super special glass' the display is 4 x jumped. I can still use the device, but when I get in a rainstorm times ....? When Sony was explained to me that there is never any guarantee / warranty on unbreakable glass! Please remember, this is for all outdoor smartphones so: on the display glass never's guarantee / warranty! means manufacturers can easily argue that this is an extra stable glass in his unit, if this is not so one has had bad luck as a consumer. Conclusion: Stay away, at least from this sony go smartphone!
