I am having this power on/off problem since I bought my N800 too, and posted that too. But let me ask you a question: Are you positive the package was the responsible? I wish you have found a final solution , but as I can see in your post , you have had the problem right out the box, so the package was'nt installed at that time, right? I am saying this because I suspect that the fault is caused by other than a package installed. Also, you have experienced the same problem with your N800 too . I've been moving from "I think I solved it, all normal" to "the failure is there again" many times. In fact, for a week or so turn it on/off was normal in my N800 but the problem is back right now I know, I always leave the IT turned on , but I have the right to turn it on/of normally at my will I am far from USA, and having bought my N there, a roundtrip shipping almost cost more than the N itself, that's the only reason I did'nt return my unit to Nokia as FAULTY unit.
