Help Desire stuck in bootloop - no space left

[Maenad]

Hi
My desire is stuck trying to boot and can't do Recovery due to there being no space left. So before i do a factory reset and lose everything in internal mem (i never got round to backing it up - my bad) is there any way i can remove a few files to free up some space so it can boot? Phone isn't rooted btw.
Thanks in advance

Edit:
Android Version: 2.1 or 2.2? Not sure which & can't check cos phone won't boot - sorry!
Network: 3 UK
Taskiller Used?: Y - Advanced task killer
[Optional]Are You rooted & which Rom: N
Issue: as above

no space left shouldnt cause a boot issue

i've seen it before. Not sure what access to /data/app/ adb has and whether it can do much from recovery on an unrooted device though
