i have been happy with my family's iphones at 1.1.4. consequently i never bothered to upgrade itunes since 7.6.2. if i upgrade to 8 will it affect my jailbroken t-mobile phone?
i miss the "just for you" section of itunes and i understand it's been replaced by genius. have there been any problems for others that are still on 1.1.4? or should i just use another music suggestion software and stay at 7.6.2

thanks
