I believe Amazon has a Kindle ebook gift program, that's basically "here's a gift certificate pre-tagged for this particular ebook, which you can use for something else in the Kindle store if you want."

Ah! Give Kindle books link at Amazon. Says it works for "anyone with an email address."

I believe he'd have to install the Kindle software to redeem it. (Kindle works on Blackberry, right?)

Ooh, and nice to know that Blackberrys have longer battery lives than Palms; I had a Sony Clie that I loved, but got tired of it dying mid-book & needing to recharge. Work is considering assigning me a Blackberry & it's good to hear I could read ebooks on it without killing its usability as a phone.

ETA: Wait, you said "conversion" *d'oh!*

If the kindle-for-blackberry program/app doesn't work for him (for whatever reason), check out Apprentice Alf's blog.
