My Iphone is driving me crazy

I went down to Richmond in Melbourne today on the way to the studio, to buy a cheap sofa , I was looking for this particular shop that sold such sofas. I'm not really that familiar with Richmond and I ended up lost.

Bloody I phone! It's has been slowly getting more erratic day by day, won't play music anymore, it's not letting now when I get emails, strange stuff.

So I'm wondering around Richmond and I realise I'm lost. I get it out and type in the address for directions. First it tells me there no service. I'm in inner city Melbourne for fucks sake! I turn it off and on, about 6 more times and suddenly it comes good, service at last. I pump in the address BUT it only downloads the two pin heads, one green and one red and a nice purple line between the two and NOTHING ELSE. no map, no street signs, just a nice grey blank screen.
This is not very helpful!
So I turn it off and on again, and again, etc. No, still just the two pins heads and the nice purple line! AND NOTHING ELSE! it would be ok if I could see two GIANT FUCKING PINS IN THE STREET TO GUIDE ME!!!
I tell you I was standing in Bridge St Richmond Shaking the fuck out the thing. I then took to asking people on the street and no one knew where this address was. I was thinking, just go to the studio, forget it, It's got far too hard!!!
And I looked down and it had downloaded the map! Bloody device!

So the outcome, I have a new, cheap, slightly damaged ( it's a studio sofa!) but very comfortable sofa arriving on Thursday.
The bastard device is going to the I phone hospital sometime this week.
