Not sure that would do much for iOS.
iOS doesn't come with garage band
i mis understood the whole post then.
if you purchased it then go to the itunes on a friend's mac and get it for free
i went on my mac and went to itunes and searched for garage band and the 4.99 price went to FREE
if the phone had garage band originally and you deleted it, then its just a matter of going into the app store on the iPhone, and going to the store, going to purchases and then selecting not on this iPhone. and if it was on the iPhone at one point because it was purchased, a cloud icon would be next to the app where you can download it again
sorry for my earlier post . i thought it was os x garage band
go to app store
click on updates
click on purchased
click on not on this iPhone
scroll down and garage band should be there. and there should be a cloud next to it.
lastly
this is an itunes problem. you are entitled to free telephone support, because of it. so if you need garageband back , and this post doesn't help. go call apple care. and tell them this is a itunes store problem and i want my garage band back and i don't need apple care, gimmie gimme gimme
and they will help you
in america, once we buy an app - even a removed app like "ultimate warrior sound board " , you can get it back for free, because it belongs to you. heck i can even redownload the iPhone 4 case program for my 6s+ because that app belongs to me
practically no one in america can download the yemin episode of a cancelled tv show called "DR DANGER" but since i bought it for $0.00 , i can stream it or download it from the itunes store anytime i feel like it, and that should be the same for your copy of garage band. if its not because of where you live, then i don't know what else to say
