Help needed about O2 tariff

thor

I've finally got my new mobile sorted out after ordering a Samsung D800 on O2 250 from mobileshop.com.
I'm trying to figure out what I can do with my 250 anytime xnet inclusive minutes per month.
From postings on this thread I know that I can call 0844, 0845 & 0870 but the t&c quoted below does not list 0844 as a local call number but I assume that it is. Also included are free phone numbers so that means 0800 & 08000 I guess.
Reading through the rest can anyone confirm the following :-

1. Picture & video messages will come out of the inclusive messages at a cost of four text messages.

2. There is 1 month rollover for O2 250 even though http://www.o2.co.uk/assets/O2HybridNav/Static-files/PDFs/PAYMTHLYPLANSFINALJULY20.pdf
says there isn't.

3. "WAP over GSM data calls" will come out of the inclusive minutes.

and finally what are " WAP over GSM data calls"? Is it some form of primitive phone internet? I really hope so because otherwise I will have about 220 minutes per month spare and going to waste.

Unused inclusive minutes and messages cannot be carried forward one month to the next except on O2 200, 250, 400, 600 and O2 Max where they can be carried over for 1 month. If you change calling plan any unused rollover minutes and messages will be lost. Unless otherwise stated, call prices are quoted by the minute, include VAT and are charged in 1 second increments, then rounded-up to the nearest second. Each call is charged excluding VAT and then rounded-up to the nearest penny. VAT is then added to the total of all charges on your bill. Minimum call charge 3p for standard voice calls and 6p for standard data calls. Prices are correct at time of going to print but are subject to change. Prices shown are for Direct Debit only. Different payment methods may incur additional charges. Use of the 100kb inclusive monthly data allowance is handset dependent. Unused data allowance cannot be carried forward one month to the next.

Until 28 September 2006, video calls from O2 mobiles will be charged at the same rate as equivalent voice calls and will be eligible for inclusion within the monthly inclusive calling plan minute allowance. From 29 September 2006, Video calls from O2 mobiles to other UK mobiles will be excluded from the monthly allowance and charged at a rate of 50p per minute. Charges for video calls start when the recipient accepts the call, even if the video call subsequently fails, therefore a failed call may be subject to a minimum call charge. Video calling is handset and network dependant. Use of 3G is subject to 3G coverage."
