Wish I knew what was going on with the iphone 5. I've had my 3gs since launch and it needs replacing badly. I broke the original screen after 18 months of abuse, made the mistake of fitting a cheap screen which lasted a week. Fitted another cheap screen and broke that inside a week too

moral is do not but cheap screens.
I'd decided I wanted to move away from the iphone and saw the HTC sensation spec, waited for it to come out and made the purchase.. Lucky for me o2 had run me through the returns procedure when I bought it (it's like they knew lol) and it went back within 14 days. You think the iphone battery is bad, try a sensation! And you couldn't even see the screen outside!
I'm not sure how long the iphone 4 design would last with me, I drop mine a lot and the glass back wouldn't lkke it.
Just wish there was some reliable info on the 5, I know apple like the secret squirrell stuff but I'm not even sure if there's deffinately going to be a 5 let alone if it's going to be different than the 4 (hardware'wise)
