I currently have iOS5 beta 1 installed on my iphone 4. I skipped beta 2, and am now looking to upgrade to beta 3. I read online that some people were having problems loading beta 1 backups in beta 3, but nothing was very specific. Anyone have any details or do I need to upgrade to beta 2, backup, then upgrade to beta 3. The device running beta 1 is my main device, so I really don't wanna lose my backup. Thanks!
