AT&T Cust, on 1.1.4, Ziphone Jailbroken (not unlocked or downgraded) many weeks ago. Out of the blue, a week ago, my stupiPhone started acting a little odd. When in its cradle, it'd start making the "I'm in the cradle now!" sound at random times. After a couple days of that, it was 50 times in a row, again at random. A couple days later, while it was sitting there, one of those sleek blue text windows (like the wiggly icon instruction window) popped up atop my springboard and said "This device is incompatible with the iPhone". Strange, I thought. What device? It went away. But came back, again at random. Then went away. Minutes ago, I push the home button to turn it on, and nothing. Power button, also nothing. Holding them down, nothing. No DFU mode, just a whole lot of nothing. One dead to the world iPhone. Got oh, what, four weeks of use a crashy mp3 player, for $600? Very nice. Now to lose another $200 for cancelling this spotty AT&T service.
