My 9900 randomly restarts, and the battery life is crap

Have any of the new OS's fixed these issues or should I take mine back to Bell to get it swapped? I'm running...if I have the right numbers - v7.0.0.0.261 platform 5.0.0.469.

My phone also is leaking a bit of light from between the bottom of the screen and the area where the call, blackberry key, back, and end buttons are.

I would update your os straight away

Its an old one you have on it now

Update the OS, you also have the warranty to take advantage of by having your carrier replace the defective keyboard's membrane, known as a warranty repair.

Update OS.
