    is there a way to defrag the iphone 3gs 3.1.2 32g or does that exist?

    I don't think that exists, or that it is needed. I think you only need to defrag if you have a hard drive (ie moving parts). As the iPhone is just a flash drive, I don't think it has to be defragmented.

    I have never come across that type of question , skaramanga , SSD do fragment data. Fragmentation exists on a solid state drive to the same extent that it exists on a conventional drive. The difference is that a solid state drive does not have something that has to move to the physical location of the data as a conventional drive does and so fragmentation does not slow down a solid state drive, but the fragmentation is still there. For all types of drives (conventional and solid state), fragmentation can waste drive space and in extreme cases cause errors.

    To the OP why would you need to defrag ? If you are having issues you can always just restore and start fresh .

    It can - fragmentation can/will cause cache misses. The performance difference isn't probably all that noticeable mind you. Another minor issue is you use up more resources tracking where the parts of the file are stored if they aren't contiguous.

    Something else to consider apart from physical storage, is that different file systems handle fragmentation in different ways. NTFS is notoriously bad at handling fragmentation, hence the need to defrag regularly. One reason is the way it allocates filespace. FAT is bad too. HFS+ by contrast, handles some defragmentation on the fly. EXT3 tends not to be as bad as NTFS as FAT because of their allocation strategy.

    That said, if optimization were really that critical - it would likely be faster to wipe and restore, than use a utility to defrag the iPhone (beyond what it's FS already does for you.)

    This is a Unix-based system we're talking about. you can't think about fragmenting in Windows terms.

    Create a FAT32 or NTFS partition on a UNIX based system, and voila, you're talking fragmentation. The OS has little to do with it.

    There can be some very limited, entirely negligible fragmentation, even on a Unix system like the iPhone is. No need to worry.

    If your JB'n Cydia has an APP called "iWipe". It writes 0's and 1's to your free space. It ensures that your deleted files are wiped clean. This is a unix package same used with MAC OS X. Not sure if this helps or not even if it's what you are looking for. It's still an Excellent APP to have ensuring your Privacy in case your iPhone is ever stolen or misused by others. Or if you have sensitive info that has been deleted.
