Very strange, phone has been working fine. Battery was fully charged this morning after it's overnight charge and phone was working. I went to work and took the phone out during my mid-morning break and it's dead. Attached it to the charger that I keep at work and still nothing after a few minutes. I took the battery and the sim card out. Battery voltage is 4VDC which is fine. Reinstalled the battery and tried turning on the phone with and without the sim card,, nothing from the phone, not every the status LED. Is there a hidden reset switch somewhere or is it pouched? The phone is only 2 months old so I'm sure my carrier will replace it if it comes to that, at which point I'll have to decide whether or not to replace it with another Xperia and or go black or white. Mine is black, but I really like the looks of the phone in white. Any suggestions will be appreciated.
