So I was told by a Sprint rep that if the phone memory gets below about 80 MB then the phone will start to lag. Well I can't seem to delete enough stuff to get back above 80 MB available memory, I deleted pics, texts messages and various apps that I would have liked to keep. I started playing with my wife's phone which has more apps then mine, I checked her available phone memory and she has 102 MB!!! I can't figure out what I could have on my phone memory that would be taking up over 20 MB of space. Where can I look to try and figure this out? My wife's phone is very zippy and quick, while my phone waits forever when switching apps. Also, How do I transfer pics I have taken on my phone to the SD card instead of using phone memory?
