And ive got another questionn ive been meaning to ask...its about my new phone

ive only downloaded three apps...whatsap, tapatalk and BT Smarttalk and now its says theres not enojugh memory to get more things. i cant get twitter

cant get facebook (I don't go there often but would like it on my phone) and it won't even update existing apps that came with the phone...like youtube. when i go into my memory, there's hardly any used on that little thing you stick in the side, just a tiny bit, so whats' going on!! i need my twitter for silverstone so i can wheedle my way into the Merc garage


what do i have to do? phone talktime or car phone warehouse again?
