I might be hopping onto the iPhone bandwagon as well, after finding out that my sister was getting the 4s. I had hopes of her selling her iPhone 4 to me but she has plans on getting a bit more cash than I'd be willing to pay, better off heading to the store and snag one. With this said, I'm going to attempt to get a 4s after work tomorrow (Not going to take the day off just to wait in line for a phone). How successful I will be is another story. If all else fails, I may just stick with the iPhone 4 since I read it has 100 hours more of battery life in standby mode.
Currently, I'm using a Samsung Impression in which now my keys like to stick when typing, writing out sentences that make no sense like "Lets. Goooo to. Great. Aaamerica today." Yes, it drives me nuts! Also, every once in a while I have to reboot my phone as when I send a text, my phone gets stuck in 'limbo' attempting to send it. Should be a nice upgrade. The Impression however does take good pictures for what it is, and can take panoramic photos.
