You will be able to download and install more than one app at the same time, even on 3G.

In iOS 5's predecessors you were only able to download only one app at a time. In case you wanted to download another app, you will get a "Waiting..." message until the first app finished downloading
a small correction, ..."Waiting..." message NOT till the first app finished downloading, rather, till the first app finished downloading and installing.
ReplyDeleteSo definetely something to look forward to!
