After doing a factory reset (or when setting up a new windows phone for the first time) it prompts me to restore from backup if I desire. Is it possible to do this over a wifi connection though? At the point when it asks me I haven't had a chance to get into settings to connect to any wifi networks so isn't it going to use a chunk of my data allowance (which is fairly small) to restore the backup?
Alternately, is there a way to trigger the restore from backup without doing a factory reset?
