Thanks, but I have absolutely no clue how all that technical mumbo jumbo works...lol. I flashed the data2ext and enabled it, but i don't notice a difference in benchmark results.

I did the adb commands, but I'm not sure what making sure the mmcblk0p2 isn't mounted anywhere thing means. I tried doing the EXT2 version. I also didn't understand what formatting the ext partition to ext2 with a 4KB block size meant. As far as total space, it says my total space is 179 MB, but my available is 118 MB. If it helps, I'm running the aospCMOD rom. Another important thing to note is that I remember the terminal telling me something like data2ext is enabled but not active.

When you type mount|egrop mmcblk0p2 what comes up when you hit enter?
It should just come up mount|egrop mmcblk0p2 and next line should be the #.
Dont worry about the partition. Just partition the card in recovery to the 1Gb one and 0 for swap.
Once its enabled, internal storage should be about 1Gb.
also the -O is the letter not the number

When i typed mount|egrop mmcblk0p2, the same thing came up, and I got a # after that. What am I supposed to do after that again? I don't know what you mean when you say "Dont worry about the partition. Just partition the card in recovery to the 1Gb one and 0 for swap.

Thanks a lot for all your help, I really appreciate it.

Boot into recovery. Scroll down to advanced and select it. scroll to partition SD card and select it. select the 1024M for ext size and zero for swap.When i typed mount|egrop mmcblk0p2, the same thing came up, and I got a # after that. What am I supposed to do after that again? I don't know what you mean when you say "Dont worry about the partition. Just partition the card in recovery to the 1Gb one and 0 for swap.

When you get back to the # continue on with the rest of the commands

Alright, I partitioned the card in the advanced menu like you said, and now I have almost a gig of space in the internal storage. Now, when I go to enter mount|egrep mmcblk0p2 in the cmd window, I get something like "/dev/block/mmcblk0p2 on /data type ext2 (rw,nosuid,nodev,noatime,nodiratime, rs=continue)
# unmount". Where should I go from here?

To give somewhat of an update, this dramatically increased my battery life. I'm not sure of anything from a performance perspective, as I can't OC very high anyways, but the battery was enough in itself for anyone to try this. I was on a full charge at 8 a.m., went the full day with regular use and I'm at 20 % at 11:30 p.m... No joke.
Had no issues following these steps:
But I can't get data2ext to work. Why? Help!!

Code:
Download the data2ext flashable zip from the first post on this XDA thread: Link.
Put the data2ext flashble .zip on the SD card.
Flash the zip using the ClockworkMod Recovery.
These next steps will ERASE EVERYTHING on your SDCARD! Backup now, then come back to this step.
In the ClockworkMod Recovery, select Advanced and then Partition SD Card.
Depending on the size of the SD card, pick the size of the EXT partition (1024 MB is the recommended MAX).
Swap isn't needed for data2ext, just keep it at 0
Reboot the phone.
Launch the Terminal Emulator (or use ADB (adb shell)) & type the following commands:
su
Ensure that mmcblk0p2 isn't mounted anywhere. You can do this by running mount|egrep mmcblk0p2. If that returns anything, the ext partition is mounted, please unmount it using this command in Terminal Emulator: umount /sd-ext or umount /dev/block/mmcblk0p2
mke2fs -m0 -b4096 /dev/block/mmcblk0p2
tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk0p2
e2fsck -yf /dev/block/mmcblk0p2
tune2fs -o journal_data_writeback /dev/block/mmcblk0p2
tune2fs -O ^has_journal /dev/block/mmcblk0p2
data2ext --enable
Reboot your phone however you would like, assuming no errors from the above commands.
Once the phone finished rebooting, data2ext should be setup at this point. You can check by looking at your free space under Settings | Storage in Android. It should be close to what size you chose in step 6, but will depend on how many apps you have installed.
Restore data to sdcard (if any was backed up)But I can't get data2ext to work. Why? Help!!

How does this increase battery life? I thought it was just to get more "internal" storage.

Can you be a little more specific and clarify what your saying?
It sounds like you might have missed a step.
And no 96mb doesnt seem right should be like 150ish.
Also its not unmount but umount, dont put the n in it. I had the same problem until it was pointed out to me I was mistyping.
