how much u pay for the phone? mac is gay and i can see u have no experience so here u go last thing u wanna do is buy anyting from radio shack unless u willing to fix the problem urself, they dont know jack chit, there are hundreds of places online where u can buy the memory, i rather buy something from a thieve n the street than take something to fix at radio shack. mmm let me guess they told u is an internal prolem. thanks for sharing ur experience i think i wanan wait a bit until they fix all the bugs and update the software on it. if it has windows thats the problem with the mac heh winblows
