AFAIK there are no such things as executable code in SMS. There are
specially formatted SMS that set or recent certain flags. For example,
there are standardized flags (and ways to set and reset them) for
voicemail and fax icons. O2 is probably using an undocumented (reserved)
flag bit for their home icon.
