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 .

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.)

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.
