I am not a developer, but I have my UDID registered on a very nice dev's account (if you're reading this, thank you!) I want to install iOS 5 today, both on my iPad 2 and iPhone 4. But sadly I might have to get a replacement soon (for both. I know right?), because I'm having a few hardware problems. But, I may not get to make that long drive to the Apple store & Best Buy for a few weeks, and I'm an impatient person, so I want to try iOS 5 now. Question is, if I go to replace them (iPad 2 @ Best Buy & iPhone 4 @ Apple Store) will I run into any problems? Anyone else done something like that? What was your experience?
