Does memory stick in the mobile makes it slow?

It depends on your mobile phone. What is the type? And what's the firmware. Actually there's alot of new launced mobile phone which can supporting up to 4 GB memory card. But only on certain models. You didn't tell here what's your mobile phone model so i can suggest what's the best solution for you. Good luck and have a nice day. Happy mylotting.

You may need to get a higher memory. I have an 8gb memory card that I am going to put in my T-Mobile Wing when I get it. I am guessing the higher the memory the more you can save and not have problems with it running slow.

I do believe that depends on how much information you have on the memory card... If you use memory card in phones, initial start up might be slower but it shouldn't affect it too much... However, once you start to fill up memory card, it tends to slow the phone down a bit...
