Ok Now to partition, Just go to recovery and hit partition, Whats a good swap-size. Do i have to wipe or do anything else before partition it?
For Mytouch, I've heard the best swap is actually zero. I would go with that, its been good for me, but really just experiment with it, see what helps your phone out the most. Probably don't want to go to high like 196MB or over, cause anything around that range just is overkill and actually hurts your phone more than helps. So I would recommend a full wipe of everything Factory reset, dalkiv cache, ext partition, battery stats, and rotation, then partition --> 0 swap, ext2 however much room you want to install roms on since this is where Apps2SD goes, I usually do 512 and never run out of room. And that is it, just let it partition, then also make sure to ext2 to ext3 in the partition menu, do this after the partition. Also do ext3 to ext4 if the rom says to, for SuperD just do ext2 to ext3.
That's it. By the way, you'll need to back everything from your sd card up, this will wipe everything. But for partitioning I suggest that, in fact you have to wipe your sd card, then you can put your partitions in. Anyway, backup, wipe, partition,
reflash your rom, reinstall your apps and settings. Done. Good Luck!
