Anyone now how to use this as just a phone, without all the additional extortionate prices?

Hi all,
I've been hacking my E3 over the last few days, but I can't seem to get my rootfs image to work...
My toolchain seems to work, as I can compile u-boot and the kernel with no problems, and they both boot, but the root just doesn't want to execute - i.e it stops after :
"... RAMDISK: Compressed image found at block 0 VFS: Mounted root (ext2 filesystem). Freeing init memory: 100K"
I've checked my inittab, and the relevant line is there:
"::respawn:/bin/ash"
I've mounted the ext2 image locally, and 'file busybox' says:
"busybox: setuid ELF 32-bit LSB executable, ARM, version 1 (ARM), dynamically linked (uses shared libs), stripped"
So I know that its compiled correctly. (unless I require static linking)
I'm using the standard linux.pbl pbltool script, so maybe I'm getting the memory locations wrong (my rootfs and kernel are slightly different sizes)
When using the stock rootfs, the system works fine with my u-boot and kernel.
Any help would be appreciated,
Tolly

Does anyone have a definitive answer as to what I need to hook up an E3 to a
PC serial port?
The various opinions I've seen so far are:
* If you just wire it up, it may work, but you run some risk of frying the UART in the E3.
* If you just wire it up, it won't work, because you need to invert the signal levels.
* You can wire it up to an E2 line level converter and it will work.
Which one of these, if any, is right?
