so i plugged my iphone into my itunes today and the first thing that popped up was a newer software version for my iphone and i clicked download and update. i noticed when i started to download the new software it says it takes 2 hours to download. i am currently in a hotel right now so i dont know if the internet here being a little slow has an effect. is this normal? does it take a little time to download the new software? also i have gotten a couple phone calls while the new software has been loading onto my phone. does that interrupt the download at all or bad for it? thanks
