Hi, I have an iPhone 4 running 4.1 and jailbroken but one speaker has stopped working, I will have to take it back to the shop but will restore it first, I will want to jailbreak it again when it's fixed. My question is, if I send it off for repair will they update the software to 4.2 (which cannot be jailbroke). When I had a nolkia and it was sent off for repair the automatically updated the software, is this the case with apple? Thanks.
