I have a 7100t this one is my third. Anyways when I get out of bed this morning the thing is dead, black,no screen when unplugged. When plugged in it works sort of all though buggy. When connected to computer with blackberry software going it wont connect. Do you guys think its my battery or could I be in worse shape?
I did install bb today and it worked fine for over a week. also there was a thunderstorm last night, could a power surge (lightening have fried my battery/ blueberry)

I love this thing as a pda/phone, but as a consumer electric device it is the most fragile I have ever had.

You may want to installing the OS upgrade posted at T-Mobile or hold off for a bit. I have heard rummors that an updated OS is due out soon. I'm not sure of the timeline tho.

Since fragility is mentioned, I'll have to chime in:

While the 7100 is better in many ways ("phone" like form factor), ruggedizedness would not be one of them from what I have heard. Although it's not too bad compared to other phones such as Treo's (Treo's are more fragile), there are stronger BlackBerries available.

For a stronger BlackBerry, I recommend the full QWERTY models. Some people have accidentally dropped 72XX series from 9 feet high down to concrete down stairwells and garages, and the BlackBerries survived. The 72XX series are among the most ruggedized phones available and almost never need to be replaced.

From this thread, it is clear that certain models survive abuse much better:
