I'm a dev and 3.1 beta 2 just ran out while im at work so I get the purple screen. Was wondering if I flash to 3.1 beta 3 on a computer that I normally do now sync with ( my work computer which is also a mac ) will I loose data or will it retain all my information? I hate not having my phone all day but am willing to wait till I get home so I dont loose everything on my phone since last sync.
