Each i-appli gets up to 10kb (you have to specify how much in the jam file)
of storage
to use.  i-applis cannot share the information in the Scratchpad, so data
stored by
an i-appli is only accessible by that i-appli.  Midlets (programs that use
Sun's MIDP profile)
if they are in the same Midlet suite can share storage, remember NTT
DoCoMo's i-appli is not a Midlet.

Well stability wise, they are pretty stable.  Granted I have not left a
phone without power for a month, nor have I violently dropped my phone on
the ground or stuck it into a power plug.
For normal usage and situations you can consider the data permanent until
you programmatically
delete it or if the user deletes you application ( then the storage bound
with the application is deleted too)

I hope that helps,
Zev
