Samsung Gleam RAM memory running out after little use?

Just got this phone, hardly used it except for mobile IM and already I'm getting notifications that the RAM is being used up. My VX-5200 had more capability than this piece of ****. Is there a fix for this or what?

Are you keeping all your text you send out and receive? If so, that is going to eat up memory.

Also, every time you download a program, it uses up memory, and any saved items that have to do with that program take up memory.

You should check to make sure that every time your using the IM program, that it's not saving all that you text too.
