i decided to jailbreak my iphone a while ago and now want to remove it after going through lots of forum posts i have read to get rid of the jailbreak i have to restore my iphone i dont have a problem with that but it says ' restore and update ' no just restore but i have heard if you update it will ' brick ' the iphone and i cant afford for that to happen, so does it matter if i restore and update or will it be fine??
