I have been having trouble with my phone running slow. After spending a few days in the nook color forum i stated to think maybe it was my micro sd card. so off to walmart. i bought an 8gb class 4 card as opposed to the stock 16gb class 2. im no longer having problems downloading or installing apps. and the icons on my desktop populate much faster. there have been times i had a 15 second wait.. also its worth mentioning that this droid is only 4 days old. mine wouldnt take the 2.2.2 update so they sent me a new one. my last phone did the same thing. so i thought what the heck.. im glad i did and it may help you too if your having simular problems..
