You need and external SD card. You can get a 16gb one from Sandisk on Amazon for $28, plenty of room on that to do anything.
Ok,
I rooted my phone using this method (the old not the one click) then I removed most of the ATT nonsense (att music, att nav... and other att pay apps).
I have about 7 gig of internal data stored on my phone, I do not have an external sim in it.
I used the one click method to install the lag fix.
I downloaded the app and it was fairly self explanatory once it downloaded I clicked on it in my status bar, cause I couldn't find and icon or anything else to load it.
It opened up and loaded and there were several options to do, one was unroot, root and a bunch of others I cant remember.
I figured I already had it rooted so I just installed the ext2 option then after that installed I clicked on the OneClickLagFix V1+ and bam it did some stuff in the backround and shut off rebooted and shut off again.
I tried to hit the power button and nothing happened till I removed the battery and then it was fine. Took about twice as long as normal to boot but now everything is fine and faster then ever.
I actually was in the process of getting a different phone or going back to an iphone since this was my first android and was disappointed. But my props to everyone who was involved to make this Lag fix cause it is bada$$.
I dont know if I did this right by not using a external sd card or not but it worked flawless. (If someone can confirm I would appreciate it, I also just used the standard partition it was like 13XX mb I think??)
Thanks again everybody and sorry for a long first post I just wanted to share my experience
