Welcome to XDA-developers!

Your ROM version is fine, however you may wish to upgrade to the latest 1.13 ROM + 1.13 Radio + BigStorage (http://forum.xda-developers.com/showthread.php?t=273911) (by the way, BigStorage is just a way in which you can extend your measly 7MB of Storage to 27MB). However you will need a USB cable for the above method: I highly recommend to invest in one anyway, as you will find installing many programs onto your JAM difficult without one.

I think it is possible to upgrade with just a SD/MMC card and a SD/MMC reader for your computer, however it is considerably more complicated and you will not be able to back up your existing ROM, as you will need your computer to command your JAM during the backup process. You will probably need to merge two upgrading methods in order to get a USB cable-free process, something that no one else has done. Sorry I don't quite have the time for that yet, but maybe someone else can come to your aid!

Is there a technical reason you can't use a USB cable by the way?

EDIT: I forgot this: the reason why you cannot upgrade by just dumping a ROM onto the SD card and letting the JAM upgrade from that is that the ROM must be modified with some special, device unique data from your JAM first before your JAM will accept it. The normal ROM upgrade programs do this via USB by retrieving the device data from your JAM and then applying it to the ROM they are about to send to it. While there is a way to manually get this required data, that too requires a USB cable (see http://forum.xda-developers.com/showthread.php?t=231410).

Please avoid cross-posting, especially since this is the wrong forum. I can't help you anyway - different models of PDA can have very different ways of doing things.
