Last night I forgot my cellphone outside and it was raining. It was still on, still working and this morning when I went to text, it turned off. When I powered it up, I got this "Use Genuine Battery" message and it was powering down counting down from 10. If anybody has had this and fixed it, what did you do? I have no house phone, this is on my only phone and I'm not due for an upgrade till May.
