how do i put large pdf files on my iphone?

I have about 3 gigs of pdf's (manuals mainly) that would be really handy to have on my 16g 3gs iphone. I have the air sharing app which I think will let me view the files, but i dont know how to transfer them. is there an app to do this?

iFile will do that without a problem. I believe its only $.99.

Ifile doesn't appear to be available in the ireland store, i found 'files' but again i dont now if it is suitable for large files. it says transfer is by wifi? 3 gigs would take a long time?

Sorry folks, please excuse my ignorance, Air sharing app seems to be working fine, i was under the impression transferring files that big through wifi would take a lot of time, but i have it running now and it seems to be going pretty fast. Sorry again!!!

I have a large PDF that I would like to be able to view from my iPhone. Can you please help me do this? I need to download an App to transfer the file to my iPhone and then I need to download another App to view the file, is that correct?

I would be interested in knowing how people view large pdf files. Ive been able to tranfer the files using air sharing but when I go to view them it pretty much just locks up because of thier size
