M,
Forget about the comment about Software version 3.0 on the iphone , this wont be an issue as it is not released yet to general public (only a BETA version released to developers on download ) what you do have to worry about is what firmware version is on the phone .
If it is software version 2.2.1 then it cannot be used on any Irish Network other than O2 as this firmware version can only be jailbroken (able to install 3rd party apps) but not unlocked (able to use on other networks ).
You cannot find out what version software is on the phone from the box you have to power it up so catch22 , buy it, open it, and take the risk ?
If you do buy it and it is ver 2.2.1 then you basically have a very expensive ipod touch .
Rumours are that there is a unlocking software for firmware version 2.2.1 but is deliberatly not been released until apple release O.S 3.0 , reason is if they release the unlock now during the 3.0 BETA release then apple will fix it before the public roll out of the full version in June/ July of this year .
You can buy factory unlocked iphone from ITALY or New Zealand for example then you have no worries as these phones can be used on any network as they are made with no restrictions due to the laws in these countries , they do not allow a phone maker to be signed to 1 network providor , they are the best type of phone to use if you wanna use a different providor (Vodafone) as you never have to worry about updating the phone and locking it again .......problem is they are really expensive circa €600
I know this has gone a little off thread but important you should know before splashing out €300.
If you do buy it and dont like it and its a 3G iphone and not running firmware 2.2.1 , i will gladly give you your €300 back for it .
My 2 pence worth.

(p.s) sorry i dont know much about camcorders etc.
