I had an Active 10 and couldn't get the details to load. Sometimes the caches would show but never the description, hint etc. I am using a mac and the SatSync for mac is still in beta so maybe that had something to do with it.
Im exactly the same. Found the iPhone app at the weekend and love it. Especially when used in tandem with a standalone GPS unit.
My son and I found our first four caches on Saturday and we cannot wait till this weekend to get out and crack a few more. I must admit to sneaking out yesterday to grab a couple and another one this morning. Cannot go anywhere without checking for caches. Totally hooked.
Browsing these forums it strikes me what a friendly bunch geocachers are. Very different from most forums.
