How do I split a string on a delimiter in Bash?

Question

I have this string stored in a variable:

IN=\"bla@some.com;john@home.com\"

Now I would like to split the strings by ; delimite

In Android shell, most of the proposed methods just do not work:

$ IFS=':' read -ra ADDR <<<"$PATH"                             
/system/bin/sh: can't create temporary file /sqlite_stmt_journals/mksh.EbNoR10629: No such file or directory

What does work is:

$ for i in ${PATH//:/ }; do echo $i; done
/sbin
/vendor/bin
/system/sbin
/system/bin
/system/xbin

where // means global replacement.
