Wing cuts off during phone call

[patspdaphone]

I wonder whether anyone has had this problem before. During a phone conversation the Wing suddenly turns itself off and drops the call. Turning it back on, results in a soft reset which can freeze at the Windows logo. Then the device can only be revived by plugging it to its charger. This happens even when the battery has a full charge.
I have removed the XD card and it still behaves the same.
I have hard reset the device to its original state and still the same thing happens.
Does anyone have any ideas about what is going on?
Thanks

im no expert but ive never heard of this problem before. if a hard reset doesnt fix it either id have to guess that its a faulty wing you should get a replacement.

I had the same problem happen to me once. I charged it for a day (took a long time to charge, too...) and then it started working by itself...
