iPhone MMS/Int'l SMS Charges

[Anonymous]

On my iPhone tariff, I get 500 free SMS a month.

Is it true that I can:

*send texts to abroad, using 4 of my SMS each time?
*send texts FROM abroad, using 4 SMS each time?
*put my SIM in another phone, and send an MMS, using up 4 of my SMS?
*use 4 of my SMS quota to send an MMS when iPhone software 3.0 comes out?

Also, will my girlfriend be able to use her unlimited SMS allowance on her W760i (Online 15 Bonus plan) to do the same?

Inclusive messages can be used for texts sent in the UK to UK mobiles, and texts sent from abroad. Sending one UK text uses one message and sending one text to the UK from abroad uses four messages.
Texts sent to international numbers from the UK are excluded from the inclusive message allowance and are charged at 12p with ITS

With regards to MMS, the people who are testing iPhone Software 3.0 at the moment are getting 4 texts knocked off their allowance per MMS Message sent.

Obviously O2 may choose to charge for this service when 3.0 gets officially released. I very much doubt they would start charging, as other Contracts just deduct 4 texts from your monthly allowance and the iPhone Contract shouldn't be different.
