Hello...I'm just coming from an iPhone 3G to the Captivate. I'm having a few frustrating issues that I can't seem to get resolved....I'll start with the email client... 1) There seems to be a DNS flushing issue when the Captivate moves from WIFI to 3G. I run a split DNS with the WIFI on a RFC1918 network and of course a routed IP when connected to 3G. The problem seems to be that as the Cap moves on and off WIFI as I move in and out of range of the WIFI signal and the Cap acquires it's new IP address, it does not expire the DNS cache and there when it tries to contact the IMAP server when going from WIFI -> 3G, it's doing so via the RFC1918 address and therefore doesn't work. Has anyon else seen that? 2) I have the email client set to get new email every 5 minutes. But it sometimes never updates the inbox until I actually go in to that inbox, then it updates. 3) It doesn't seem to keep a history of email addresses I've used for fast completion. For example, if I email Bob@accountemps, every time I send Bob an email, it doesn't remember that I've sent Bob an email before, and I have to type the entire address again. My primary use of the smart phone is an email client, and these issues are really frustrating to me. Thanks for any help!
