Ok, the title is a bit misleading because I kinda caught what my phone was doing and searched before posting.
Little bit of history:
When I bought my tmobile nokia it didn't have the screen sticker on it and the battery looked frayed around the edges near the connector. It was a dog w/ bluetooth and they exchanged it four days later with no hassle. Stupidly I kept the battery and reloaded my phone backup to the new phone.
Recently: My phone has been turning itself off randomly and fexplorer reports a different battery charge than the phone thinks it has. It also throws static through the headset when it's in my pocket and I move at all (regardless of where I am).
Just now: My phone beep and put up a message 'dos app closed' or 'dns app closed' (I had started my phone and not used it for over 8 hours when this happened. No connections only bluetooth active and nothing ever connected to it. The backlight wouldn't work at all so I switched it off. It would NOT turn on 4 times when I pressed the power button. I unplugged it then tried it, then plugged it in and tried it, then finally had to take the battery out and then it started up.
T-mobile said they would send me out a new phone based on other issues (I somehow worked around), but I REALLY DON'T WANT a new IMEI number.
I had to get by phone relicensed once already for software and I don't know if I can get it done again.
Any ideas on what's happening here? They wouldn't send me a new battery.
Thanks for any suggestions.
