Not sure what to do this time. A friend of mine brought me his iphone. It is a 1.1.3 OTB 8gb iphone, that was unlocked with the downgrade method to 1.1.2 then 1.1.1 oktoprep, etc. Remember that one, right? So, it is working ok, it had Installer but then he installed some apps and installer dissapeared. So what should i do with no risk of bricking it to update to 1.1.4 with fully phone functions and everything working. In General, about it says this:
version 1.1.2 (3B48b)
Please guys need your help, tell me everything you know and make me fell confident about bricking risks.
