Help, this phone is possessed!!!

Question

I have had this phone since early December. I have kept it in great quality, keep a durable case and screen protector to keep it from breaking. I have never dropped it severely or ever had water damage. The other day my phone was being really slow, which I am pretty used to anyway. But I was going to check my text messages and I touched the pull down notification bar, and when I did it pulled it down and pulled it right back up without me touching it. And ever since it has pretty much just lagged horribly, and everything I try to command it to do it goes to the application, media, messages, internet, and then closes it without any warning in seconds. I can't check my messages, call anyone, and when I tried removing the battery and restarting it, it would flash the unlock screen multiple times for about five minutes, just flashing that menu. When I tried typing in my password it would stop typing and clear the whole bar for my password. When I eventually got it to turn back on, when I went to use the lock key it instead of locking my phone it would automatically type in mnn into the search bar and give me results for mnn. Half the time the touch pad doesn't work, or the keypad doesn't want to work. I have no idea where all these problems came from, I haven't dropped it, updated anything, nothing to agitate my phone... Should I just call TMobile for a replacement or is there something I can do to salvage my phone?
I have never really had a problem up to now, other than lagged, and the App store never wants to run or run my apps for that matter. But I love the look of the phone and the keyboard. I don't want to have to get another if I can avoid it, but its not even letting me communicate now. Please Help ):

Hi and Welcome to the Community!
I recommend you attempt to boot into Safe Mode:
KB17877 How to start a BlackBerry smartphone in Safe Mode
When successful (it may take you some experimentation to get the key sequence correct), you should consider an OS reload, if you are that adventurous...here is a procedure:
At the top of each device forum, there should be some "sticky" threads that discuss the OS levels available for each model. Please use those as reference as you proceed.
From a PC, you can install any compatible (e.g., for your exact BB Model Number) OS package to a BB via this procedure:
http://supportforums.blackberry.com/t5/BlackBerry-Device-Software/How-To-Reload-Your-Operating-Syste...
Note that while written for "reload" and the Storm, it can be used to upgrade, downgrade, or reload any BB device model -- it all depends on the OS package you download and install to your PC. You can even use a different carriers OS package by simply inserting, between steps 1 and 2, the deletion, on your PC, of a file named VENDOR.XML. Be sure that you remove, from your PC, any other BB device OS packages as having more than one installed to the PC can cause conflicts with this procedure.
If you are on MAC, you are limited to only your carriers sanctioned OS packages...but can still use any levels that they currently sanction. See this procedure:
KB19915How to perform a clean reload of BlackBerry smartphone application software using BlackBerry Desktop Software
Failing that, formal support from your carrier is certainly always an option.
Good luck and let us know!
