I've got a Sprint Pre OS 1.4.5. I love the phone. I may be travelling to Europe(Ireland). What functionality, if any, will I have with the phone there? Will I be able to access the web, text, voice? Are there any modifications that Sprint or I could make that will make it usable there? Any idea on costs associated with using the phone in Europe? Roaming, long distance, etc. Thanks for any help.
