International ROMs

[slight22]

Good afternoon everyone

I'm going to Ireland here in October and i want to talk my HTC TP2 (world edition) phone with me. I gave telus a ring and they told me the following.

1) they need to activate an international roaming feature which requires a 200 dollar deposit.
2) Then i need to pay for any international Airtime (which was expected)
3) Date will cost me 25 dollars a meg. This to me is the worst because thats all I really need. I don't need the phone.

I have no intentions of giving into Telus's demands so really here's my question. As I said I'm using a world edition HTC touch pro 2 loaded with Mighty Mikes latest rom. Is there an international or European version of this rom (or something similar) i can load up so that I can use my phone in Ireland without it actually needing to go through telus? Like i said data being the most important thing to me.

thx
