ha! it’s so funny you say that. i asked my kid about doing that because, you know, save space (like, i think the mail program bites). he advised against.
on iphone i’ve manually deleted all the extra language stuff. several restores were because of iphone apps i deleted. you can delete some, but others will zap the phone. i basically quit doing that. and put on not quite so much stuff (i have hundreds of apps on my phone, mostly from cydia).
just say your note: i must have done something wrong. didn’t get the install part. will try again later. you are so cool. i really appreciate the help, because right now no one who’s here gives a crap about this so i have to figure everything out on my own. which takes a long time! and i don’t want to do anything that will hurt my new mac.
