[iMore Question]

Hi all,
I am new to this forum and apologise if this is covered else where,
I have had alook around and can't find the answer so here goes,

My husband has a iphone4 unsure of the iOS software, He brought it second hand and already jail broken with cydia on it,
I want to update it to the latest version for him,
He don't really have any apps on it that we want to keep, he does have tom tom Europe on it which he would like to keep but as this was put on for him I'm guessing though cydia or something I am unable to keep it,
If this is the case it's not too much of a problem,
So basically how do I update his phone the easiest and simplist way?
I'm not too good with techy stuff,

Sorry it's abit long winded,
Thanks in advance x

Use the cable you got with the phone and use it to connect the phone to the computer. In iTunes Apple – iTunes – Everything you need to be entertained., there should be a notification that has iPhone written on it. Just click on that and click on restore. After that, the phone will restore to the latest version of iOS and won't be jailbroken.
