I don't know if I've said it here before or not, 
but as a listowner of another internet discussion 
list, I have **ALWAYS** told people the following:

-- NEVER share your e-mail account with anyone.
-- NEVER let anyone, family included, know your 
password to your account.

I'll add to this: NEVER EVER have an e-mail 
account without a password. (I've never heard of 
an e-mail account without a password!! 0_o)

It doesn't matter who you think you can trust or 
not - people on the Internet will consider a 
message from your e-mail account to be *you* 
speaking. It doesn't matter who is actually at 
the keyboard. And unfortuantely, these same 
people will usually not accept explainations that 
the mail came from "someone else". Especially 
when you use your account for business 
transactions, it needs to be 100% private to you.

As for how to deal with the situation, it sounds 
like you've done the right thing. I would think 
that (especially if you'd already sent payment 
for the cels in question) whichever dealer 
refused to accept your explaination, might be 
swayed by receving a payment dated as being sent 
*before* they received the bogus e-mail from your 
brother.

In the case of your brother, well. . . I don't 
know what to say there. I think you need to speak 
to your parents and tell them that if he thinks 
this is oh, so funny a prank to pull - especially 
*AT* *HIS* *AGE* - they might *REALLY* want to 
come down on him. If he continues to think it is 
funny and does it to someone else, say, in an 
office environment, he *WILL* be brought up on 
criminal charges.

Unfortunately, the real bottom line is that he 
should have never been given the chance. It is 
YOUR responsablity to guard other people's access 
to your e-mail account.

Many Sharp Smiles,
