how annoying is it when you just want to install an app and it keeps giving you the message there is not enough space free to install this app!

Well there is a bit of a trick to it, well not so much a trick as a stupid feature of the iPhone OS. Now this isnt really much of an issue most of the time, unless you happen to be using some of the giant app’s out there like the tom tom europe or usa. These come in at about 1.8gig and 1.6 gig.

So basically, if you have freed up heaps of space on your phone and its still giving you the error, keep removing stuff. According to my research, you actually need about twice as much space free on the phone as the size of the app. so with a 1.8gig app you need about 3.6 gig. Now im not sure why this happens, maybe someone can enlighten me. I would be guessing its because apple decided that instead of using 1024 bits per byte, they rounded it off to 1000. And another reason may be that when copying the app to the phone it creates a temp copy of it and then moves it to the real file. So in reality you may even need more than twice the space on the phone for the app.

Anyway for those of you with giant 32 or 64 gig iphones i guess this isnt so much of an issue, but poor me with my 8 gig iphone, has to almost format it just to install one app!
