Can I download Wikipedia to my Sony Ericsson K750i?
While I’m not answering your main question, I can inform you that is is indeed possible to buy larger memory sticks for your phone. The k750i uses ‘Memory Stick Pro Duo’, which I’ve seen up to 2GB in-store and Sony have recently announcned 4GB models on the way. Also, if you are only copying the most recent revisions of articles (rather than all the respective histories, too), the database is under 1GB. (At least, it was when I last checked) I hope that helps and I hope that someone else more knowledgeable than myself can answer your other questions.
