i installed the msn app and it was working. But the installer wouldnt fully close dso I had to turn phone off.
Now it wont switch back on. Nokia logo and light comes on and light comes on if i press a buttong but it never gets to the stage of asking me for my pin code.
I had the same issue on mine mate, not long after i got it. I had to reset the phone, and lost everything :(
I think, as far as i remember...you turn the phone on, and hold green call key, 3 key and left soft key. (This key combination might be wrong so have a quick search)
I couldn't get anything else to work with mine, so it might be your only choice. :S
Sorry to hear of your problems you should be able to remove it from the app manager hopefully and i agree with what you say this is why i now only install apps i actually really want or need and that i am really going to make full use of. Although it appears some install 20+ apps if you don't need to i wouldn't install just anything as i also feel the more you put on the device the greater the chance of a conflict or problems occuring.
