I feel really stupid asking this. SInce alot of people on here really know their stuff but here it goes. Im reading these tips and tweaks and am totally lost. How do I even get these files on my phone?? Do I save them to my computer?? Do I have my cell connected to my pc? I seriously have no idea what to do. Im reading these forums like wow, I wish I had that and OMG thats sooo awesome. But then I'm like ok I see files on here but what do I do?? I must look really retarded :0(
