Hi, When i purchased my iPhone 4 the forums where awash with stories of some screens being washed out or known as warmer. The shops demo models were more of the baby blue colour. I've not got the iPhone 4 s yet and was wondering if any new owner has checked theirs to see if the colour is more defined. Anyone also checked out the iPhone 4s to see if the death grip/antenna gate still exists. Do you lose signal if you bridge the gap of the antenna on the lower lefthand side ? Is the phone faster ? Was it worth upgrading from an iPhone 4 to 4s ?
